MYSTERY PROBLEM: Credit Card Not Working

[shervin]

Many users are calling with problems unable to go through checkout with Authorize.net credit card processing... they don't even say what's wrong, but "they can't get past a certain point". Some got Credit Card Errors. The thing is, everytime *I* test it out, it works fine. So I have no idea what's going on. PLEASE take a look and help me figure out what's going on. NOTE: I scripted a UPS Shipping Calculator form into the product_info pages (not a module, wrote it myself).. I hav eno idea how this would affect it.

I couldn't get past the shipping page - your UPS module is displaying an error. It cannot pull prices if you haven't set your zip code in Configuration > Shipping.

 

I got to the payment page by hardcoding it into my browser address bar (clicking Continue on the shipping apge did nothing). I put in an old CC number of mine - seemed to work fine (it was declined).

That is strange. It works just fine for me. And my zipcode is set.

I would not know how this works ... I viewed your html source code and your nesting several forms into each other (will never work) and nesting several complete html page blocks into each other also ...
