Quick Question - PayPal

Using the latest version of WP, Gravity Forms, & PayPal Standard plugin...

Upon clicking submit in my form I end up on this page:
http://dl.dropbox.com/u/1220621/gravity-forms-forum-post-01.jpg

instead of a page resembling:
https://www.x.com/sites/default/files/paypal-01.jpg

What do I need to look at to correct this?

I received this information from PayPal's merchant support team:

Here is a copy of the headers your site is sending to PayPal:
https://paypal.com/cgi-bin/webscr?{business:billing@domain.com}{cmd:_cart}{return:http://domain.com/?page=gf_paypal_ipn}{item_name_1:Something}

The issue you're having is because the values aren't being passed properly. It should be formatted more like this:
https://paypal.com/cgi-bin/webscr?business=billing@domain.com&cmd=_cart&return=http://domain.com/?page=gf_paypal_ipn&item_name_1=Something&upload=1&amount_1=2.00

I added the "upload=1" and "amount_1=2.00" myself to get the URL to work properly.

How can I fix this according to PayPal's instructions?

Am I able to DM you or something? There's passwords required.
