Currency problem using comma as decimal point (shop in europe)

[DrByte]

Edit your /includes/modules/order_total/ot_gv.php file and add a comma into the list of allowed characters, like this:

    // clean out negative values and strip common currency symbols
    $_SESSION['cot_gv'] = preg_replace('/[^0-9.%,]/', '', $_SESSION['cot_gv']);
