Maybe KolAsin (moderator) could provide an EXTRA code here, but he would need a link to the shop.

Hello With the link posted by KolAsim I have this one by example

The code to add into the catalog page properties is here

And the full modified code is.

<script>
/** A script to display the price from ethe catalog page and to add another information price in other currency **/
/** The price into the cart will be ALWAYS in Euros in our case. Currency choosen during project creation **/
/** -- calcolo e aggiunta IVA x WSx5 by KolAsim -- **/

$(document).ready(function () {//K<;
setTimeout(() => {//K1>;
$('.im-cc-wrapper-row').each(function () {//K2>;
const rawPrice = $(this).text();
const priceCleaned = rawPrice.replace(/\s/g, '').replace('€', '');
const price = parseInt(priceCleaned);

if (isNaN(price)) return;

const changevalue = 0.51; // for the change value. . 0.51 is the actual value for change with bulgarian currency

const euros = Math.round(price); // Price in Euros
const lev = Math.round(price * changevalue); // Price in BGN for Bulgarian currency. 0.51 is the value for change

const formatEur = num => num.toLocaleString('fr-FR').replace(/\./g, ' ') + ' €';
const formatFt = num => num.toLocaleString('bg-BG').replace(/\./g, ' ') + ' лев';

// To display price infos in Euros & BGN
const ivaHtml = `
<div class="vat-calculation" style="font-weight:normal;font-size:12px">
Euros: <strong>${formatEur(euros)}</strong><br>
Info in Lev: <strong>${formatFt(lev)}</strong>
</div>`;

$(this).append(ivaHtml);

});//K2<<;
}, 800);//K1<<;
});//K<<;
</script>

Hope this helps...

Now you have the hand to modify it.

KolAsim once mentioned that JavaScript cannot interfere with the shopping cart calculations; in that case, the developers of WebSite X5 would have to do it.
