my buy-now button with menu choices "breaks" and stops working properly

[GMHounds]

after some time it starts charging customers with the last item on the menu no matter which one they choose.  This has

now happened to me three times.  When I create the button it works fine.  Days go by with happy customers and then suddenly it starts to charge them for the wrong item
