Any code Ray had implemented would have been specific to the existing power store checkout page.
I Would need to see the original checkout pages to be able to troubleshoot. really, where you have red=one the checkout, i think the quickest way to get any custom coding issues sorted is through premiere support. I don't know the code ray had implemented before, so it's going be tough for me to troubleshoot. Through premiere support, ray will be able to troubleshoot.
