problem with form and integration

Hey. I have a dropdown menu (for rss feeds) and I'm trying to intergrate it into my forum - what happens is, when you select one of the items and click submit, the page reloads - but it's still showing the default selection.

Could anyone offer any suggestions about how to fix this? (Please have a look at my website for an example. It's on the right side of every page)

Thank you,

Ahni
