Paypal confusion

[quote author="adamp1" date="1204812446"]This shouldnt be a problem. When I used PayPal I made it return the data in a POST variable. Then you have no problems. Are you using the PayPal Library from the wiki?[/quote]

How do you make Paypal return in a POST?

Yes, I tried the library, I got errors that I didn't have time to fix. I'm not done yert, but I used another, non-CI library which completed a transaction (so I could remove any issues that may have been server or Paypal related as to getting this to work).

I'd love to get it all working nice and the Paypal POST would be great - as that would eliminate the URL error message, so, any hints on how to do that?
