This project is for those who've lot of experience working with OsCommerce Payment modules - especially 2Checkout.
I've an oscommerce store installed at following URL:-
[url removed, login to view]
Everything else is working fine except the 2checkout payment module. When a customer selects 2CHECKOUT in payment options dialogue box and proceeds to checkout, he encounters an error message instead. The error msg displayed on 2CO website is like:- "Incorrect parameters were supplied, therefore this purchase cannot begin."
To recreate the problem, go to [url removed, login to view], select a few products, and then try to checkout using 2CHECKOUT payment option. I need this fixed as soon as possible.
