I changed your variables in the button form to my account then pulled the headers using Firefox's "
HTTP Headers" add-on, and this is what I see in the Headers:

That tells me that it posted the variables to the return URL which I set as
http://www.ndswebdesign.com/ I did however remove the following line of code:
Code:<input type="hidden" name="upload" value="1" />
The Upload command is only needed with the _cart cmd not the _donations cmd. That may be the issue. Try removing that.
Also you may want to change:
Code:<input type="hidden" name="phone" id="itemPhone" value="" />
Use the "night_ phone_a", "night_ phone_b", "night_ phone_c" variables instead. Check the below URL:
https://cms.paypal.com/us/cgi-bin/?&cmd=_render-content&content_ID=developer/e_howto_html_Appx_websitestandard_htmlvariables#id08A6HI0J0VUThat is the PayPal HTML variable reference for prepopulating PayPal pages, it has all of the variables on that page you just have to scroll up.
