going nuts

(gah) I inherited a site and well its a pain in the but.
This page:
http://gateway.rossoptical.com/php/product-beamsplitters_cube_detail.php?s_sort=beamsplitterscube.partnumber&s_item=beamsplitterscube.partnumber&s_word=
needs to take the selected checkboxes value (via post right now) and dump it into another form.

and on the other form this code does not work!
$partnumber = $_GET['ReqInfo'];
echo "Partnumber = ","$partnumber";


weeee!

I can make the first page use link as the method and get a url like this:
http://gateway.rossoptical.com/php/req.php?B-CHC013=ReqInfo&REQINFO=Request+Info
the value of ReqInfo is what I want.

when I find the person who did this previously (not IF) I am going to pummel them something harsh.
so I am loosing my mind, any ideas?
