Help with simple auth.net form

Hey all,

I've been trying to integrate my authorize.net account with my site and have had moderate success. Basically, the only thing I've been able to configure to actually process transactions has been an osCommerce cart.

Problem is, I'd like something more simple than a shopping cart, just a simple form or something.

I've tried to use the sample code that authorize.net provides, but I don't really understand it at all -- same with Greg K's post on here.

I have enough knowledge of auth.net in terms of finding the info I need, it's just integrating it that has been a pain.

If anyone has any ideas I'd love to hear them.

Thanks.
