I am working on a product, building from previously existing products, this is a page within the admincp.
I am wondering why sometimes I am able to pull a GPC variable and other times I am not, I am having this issue in multiple spots but this is just the smallest one to give the example.

I am able to pull the productid with:

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

But I cant get the catid to pull:

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

This is the complete page in question, Just a simple confirmation page.

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

A way I get around this is to use a query, but since I can pull the productid, I just dont understand why I cant pull the catid, when they were both submitted through the same form.

This is how I currently solve this problem:

Block Disabled:      (Update License Status)
