[Assigned] shipping settings - no 2. currency possible etc.?

I have been waiting for some days now.
But it turns out that the problem mentioned is the lesser problem.
The BIG problem now is as follows:
The checkout is not working at all.

What I Want:
- Shipping according to weight rates - and a possibility to chose pickup at warehouse
- 50 % deposit that is drawn in by OnPay (card payment) when ordering - checkout showing the amounts for payment now - as well as for payment later when goods are delivered.

What I Experience:
- checkout that does not show order panel on the right side (only address etc.)
- no possibility of checking if 50% deposit works or not - or if clients get a proper information about terms concerning 50% payment now - 50% payment later

What I Have Tried in Order to Trouble Shoot and Solve the Problem:
- deactivated all snippets conc. checkout and cart
- deactivated OnPay
- deactivated all shipping set ups
- trashed the checkout with the missing right panel
- created a new checkout with WP tools

What I Find Now:
- checkout still not showing right panel with order information
- going from cart to checkout - the checkout is not loading - meaning it is not possible to access checkout from cart

Please help ASAP

Hi again,
Well - as it turns out. I did only partly manage to solve the problem with the checkout.
The issue concerning 50% deposit is not solved in relation to OnPay. The amount which is passed on to OnPay and drawn in is the total - and not the deposit of 50%.
the code which I placed in "code Snippet" is as follows:
/**
* 1. TEKNISK (BLOCKS): Halver beløbet i det nye Blocks-checkout
* Dette rammer ordren lige før den gemmes og sendes til OnPay API'et.
*/
add_action('woocommerce_store_api_checkout_update_order_meta', function($order) {
$current_total = $order->get_total();
$order->set_total($current_total / 2);
$order->save(); // Vigtigt: Gemmer ændringen i databasen
}, 10, 1);

/**
* 2. VISUEL INFO: Besked i toppen af kurv og checkout
*/
add_action('wp_head', function() {
if (is_cart() || is_checkout()) {
$is_dan = (defined('ICL_LANGUAGE_CODE') && ICL_LANGUAGE_CODE === 'da');
$msg = $is_dan
? 'Bemærk: Du betaler kun 50% nu. Resten faktureres ved levering.'
: 'Note: You only pay 50% now. The balance will be invoiced at delivery.';

echo '<style>
.custom-deposit-info { background: #e0efff; color: #004a99; padding: 15px; text-align: center; font-weight: bold; border: 1px solid #b3d7ff; margin: 20px 0; border-radius: 4px; }
</style>';

echo '<script>
document.addEventListener("DOMContentLoaded", function() {
var target = document.querySelector(".wp-block-woocommerce-cart, .wp-block-woocommerce-checkout");
if (target) {
var div = document.createElement("div");
div.className = "custom-deposit-info";
div.innerText = "' . $msg . '";
target.parentNode.insertBefore(div, target);
}
});
</script>';
}
});

/**
* 3. VISUEL BEREGNING (HVID/FED): Vises i højre panel
*/
add_action('wp_footer', function() {
if (is_checkout()) {
?>
<script>
document.addEventListener('DOMContentLoaded', function() {
const observer = new MutationObserver(function(mutations) {
const totalElement = document.querySelector('.wc-block-components-totals-footer-item .wc-block-components-totals-item__value');

if (totalElement && !document.querySelector('.custom-deposit-row')) {
let totalText = totalElement.innerText;
let cleanTotal = totalText.replace(/[^\d]/g, '');
let totalNum = parseFloat(cleanTotal) / 100;

if (!isNaN(totalNum)) {
let deposit = (totalNum / 2).toFixed(2).replace('.', ',');
let isDan = document.documentElement.lang.includes('da');
let label = isDan ? 'Heraf betales 50% nu:' : 'To be paid now (50%):';
let currency = isDan ? ' kr.' : ' DKK';

const depositRow = document.createElement('div');
depositRow.className = 'wc-block-components-totals-item custom-deposit-row';
depositRow.style.cssText = 'color: #ffffff !important; font-weight: 900 !important; padding: 15px 0; border-top: 2px dashed #ffffff; margin-top: 10px; display: flex; justify-content: space-between; font-size: 1.25em;';

depositRow.innerHTML = `<span>${label}</span><span>${deposit}${currency}</span>`;
totalElement.closest('.wc-block-components-totals-footer-item').after(depositRow);
}
}
});
const target = document.querySelector('.wp-block-woocommerce-checkout');
if (target && observer) { observer.observe(target, { childList: true, subtree: true }); }
});
</script>
<?php
}
}, 999);

The problem is apparently that the block system does not accept the codes, - no matter how I do it. Could you please help with this as well. Thank you.

Hi Pawel,
Please concentrate on the issues that are relevant. I never mentioned currency problems or price problems for the products.
I have waited for 8 days for help with the checkout. Why you start with something completely different - I really do not understand.

Ref. product prices) No, the product prices should not be converted from Euro. I do not want the prices in DKK to follow Euro prices. For a lot of reasons. I have made fixed prices which works without any problems.
I do not understand why you have taken up this matter at all. I do not have problems with the prices or the currencies for the products. And I do not want to change that.

The problems that I have, which you should concentrate on:

1st priority:
1) The checkout page - the English checkout with ID 6080 does not connect with the Danish checkout page with the id 6077. WPML reports that my site URL has changed (ATE Server Communication error).
Because of this:
• The Advanced Translation Editor is locked
• I cannot connect existing translations
• Language box is greyed out
• Checkout translation cannot be linked to its original page
There is no “Reset ATE connection” or Troubleshooting option available in my WPML Support page.
Could you please reset / reassign the ATE site ID for my installation?

2nd priority:
2) I want to draw in a deposit of 50% via card payment (OnPay) - not the total amount - and later invoice the rest at delivery. The block set up does not accept my codes (code snippets). Tell me what to change in the code to make that happen - as I do not know where the issue occurs. Deposit plugins do not work, as they calculate pr. item - not 50% of total order amount.

3rd priority:
3) I cannot set the shipping costs in fixed DKK (secondary currency). Either you fix that - or you tell me how to get WPML to calculate (not display!) with decimals (from Euro) - in order to display DKK prices that are not with decimals.
This should not be solved by changing the whole price policy on my page. If WPML shipping cannot be displayed properly in secondary currency, I will accept that - and live with this flaw. Tell me if that is the case.
