[FX.php List] Problem with double submissions

[Bob Patin]

Only problem is that it goes to Authorize.net first, which is where their credit card gets charged.

So I need to prevent them from getting charged twice.

I think the issue right now is their web server, so I'm having them reinstall WPE for the 3rd or 4th time. I'll just say that I NEVER have this sort of problem on my Mac servers...
