(It > En) ... if you're not satisfied with the program options and this FAQ, How to set and manage the VAT on the store : WebSite X5 Guide, please wait for the STAFF's opinion from tomorrow onwards...

Így szeretném beállítani.

Van rá mód hogy így jelenjen meg az ár?

...while you wait, post the link to your cart page so we can evaluate it...

Hello Laszlo,
unfortunately the software does not include an option to display both the net and gross price like that.
I remain available.

Online translation:

Szia Laszlo,
sajnos a szoftver nem tartalmaz olyan lehetőséget, amellyel egyszerre jeleníthető meg a nettó és a bruttó ár.
Továbbra is rendelkezésedre állok.

... I calculated that you applied a 27% VAT...
... EXTRA, with my invention that I showed you, adjusting it for your page, you could get this simulated result in this STAMP of mine:

.

Ez így tökéletes lenne. Hogy tudnám ezt beállítani?

...I'm back now...
...if you're interested in the results of my simulation, let me know, and I'll be back here tomorrow to develop the code for your page...

ciao

.

Igen, érdekel! 

Köszönöm!

...OK...I'll be back here tomorrow during the day...

.

... OK ... this is the code for your linked page, to be pasted in Step_3 in Page Properties > Expert section, option > Before closing /HEAD tag:

<script>
/** -- 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('Ft', '');
const price = parseInt(priceCleaned);

if (isNaN(price)) return;

const iva = Math.round(price * 0.27);
const total = Math.round(price + iva);

const formatFt = num => num.toLocaleString('hu-HU').replace(/\./g, ' ') + ' Ft';

const ivaHtml = `
<div class="vat-calculation" style="font-weight:normal;font-size:18px">
+ Áfa (27%): <strong>${formatFt(iva)}</strong><br>
Bruttó ár: <strong>${formatFt(total)}</strong>
</div>`;

$(this).append(ivaHtml);
});//K2<<;
}, 3000);//K1<<;
});//K<<;
</script>

Köszönöm a segítséget, de valamiért nem működik, mit kell még csinálnom hogy működjön?

...in the source code of your online page (Ctrl+U), I don't see my code applied...
...when you're done, let me know...

.

az egészet bemásoltam.

szerverre másoltam, ott sem látok változást.

...I'm sorry, ...but you didn't do something correctly...
...my code doesn't exist on the online page gyorsvarrogepek.html...
...the online site is still the one from July 26th...

.

Tényleg rossz helyre raktam a kódodat!

Mostmár működik.

Hálássan köszönöm a segítségedet!

... it's OK now, ...although it needs a refresh the first time... ciao
