I believe there is no code displaying the currency. The currency symbol comes from the ecart_object page
<?php
//WA eCart Include
require_once("WA_eCart/name_PHP.php");?>
This is the corresponding code on the eCart page
<?php
// eCart Language Pack [Ge]
$name = new name_Definition("name", 0, "€ ", "", true, 2, 0, "kg", true, 3, 1, 1);
$name->cartAction = "";
$name->redirStr = "";
?>
I added the  , which works for every other page (catalogue, cart, checkout pages), but not the detail page.
I attached the detail page. This is the code displaying the price:
<label id="pricelabel"><?php echo $row_rspricetable['price']; ?></label>
