the code I have is:
var theForm = document.getElementById("WA_Store_Cart_1_ATC_<?php echo $row_WADAProducts["ProductID"]; ?>");
xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==4)
{
if (xmlHttp.responseText != "") {
var theRet=xmlHttp.responseText;
var thePriceField = "$"+ getFromRSDump(theRet,"ProductPrice");
if (thePriceField.indexOf(".")==-1) {
thePriceField += ".00";
}
if (thePriceField.indexOf(".")==thePriceField.length-2) {
thePriceField += "0";
}
is was able to get it to use the comma by changing that to:
var theForm = document.getElementById("WA_Store_Cart_1_ATC_<?php echo $row_WADAProducts["ProductID"]; ?>");
xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==4)
{
if (xmlHttp.responseText != "") {
var theRet=xmlHttp.responseText;
var thePriceField = "€"+ getFromRSDump(theRet,"ProductPrice");
if (thePriceField.indexOf(".")==-1) {
thePriceField += ",00";
}
if (thePriceField.indexOf(".")==thePriceField.length-2) {
thePriceField += "0";
}
