Frames Refresh Error

I am not a fan nor developer of frames, but I don't have the luxury of rewriting my company's entire software today, so I'm stuck. Anyway, I've figured out how to change the content of the top frame to show a new CSS styled layout. If the bottom frame changes, and I click on the home link in the top frame, I now get two of the top frames. Here's the kicker, if I hit F5 or manually refresh otherwise, the extra one goes away, but if I put a meta tag in the header of the top frame's html file to make the page automatically refresh every few seconds, it does not go away. The output for the top frame is determined by an if statement (all done in ColdFusion) and the contents of all the other possible top frames are just tables and images, and they work correctly and don't have this problem.
Thanks in advance for any help you can give me in not getting two of the same top frames there in the first place!

The problem is that I was using "mainFrame" for the target instead of "_parent". This is what happens when people need to update code they don't understand, they get frustrated because they don't have a clue what they're trying to do. Oh well, at least I learned something today

For the record, frames aren't evil... they're just often used in places they shouldn't be

Glad you were able to solve the problem
