Ray, I am so embarrassed to admit my mistake with the productoptions table. I had changed one the table field names, midway through my database development process, from ProdID remotely to ProductID locally. After exporting and uploading the productoptions table to my database, viola! Problem solved. I thank you hardily for your help in debugging this issue.
However, that still leaves the credit card display issue not being in focus. You will see exactly what I mean when you try and make a purchase for a mobile browser. Just add any item to the shopping cart, click checkout, fill out the name and address forms, click continue and you will see the problem clearly. The credit card payment field should come into focus but instead sits at the bottom of the page. Can you please have a look at the files while you still have FTP access? I appreciate your help.
By the way, I just upgraded to the new Databridge 2.3.4 and I am enjoying the new functionality. Looking forward to building more and better websites in 2019!
