Can you fix this ridiculous mess with registration!? First of all IT DOES NOT WORK and I don't want to spend time doing all the tricks that you require. How about you do all of the magic under the hood when you process a buy order?
and yes, I cannot post a screenshot here in the forum, so all I can say is that the web site says that "Error" "Failed!". (in 1995 I'd attach an image, in 2019 Ctrl+V has to be able to paste screenshot, just like in gmail or any other modern web app).
