How to search specific forum category

I am trying to do a keyword search of a specific forumcategory, however, whenever I select "search", it returns postsfrom all of the forums categorys and not just the one I specify.

Heres what I am doing.
1. select "advanced search"
2. type my search text in search box
3. select the forum to search from list box on right
4. hit "search" button

I get results that still include all forums???

What am I doing wrong?

Thanks for any help.
