97 Jetta GT with brake light problem

I have a 97 Jetta GT where the brake lights don't work. The parking lights, turn signals and warning flashers work fine. I've checked the fuse and bulbs and both are fine. It's apparent to me that the problem is somewhere in the electrical line. Just wondering how much money I stand to spend to get this fixed. Or if anybody else has any other suggestions for me to try.

Thanks in advance!

Are you sure the bulbs are stock onec? The silver ones.
I've heard of people having problems with the bronze colored once.

The ones that I tried were with the bronze base. I'll try the silver ones and see if that makes a difference. Thanks!
