Help with frames

[TrollSlayer]

I have a framset created in which I want FrameA which is on top to contain links. When these links are clicked, they should be loaded in FrameB. What I've done is use the code:

<base target="main">

This has worked perfectly on all but one link...any idea why one specific link wouldn't work...the link I'm trying to use is to a forum, so I'm not sure if it could be some setting on the forum that doesn't allow it to be opened in frames?

I think a little more information is in order. You say you're trying to use this on forums, well what kind of software are you using. At this point though I don't think that's the problem. All you've posted however is a single line of code and asked us to derive a solution based off that. The best advice I can offer you without a larger sample of the code is check it for typos. A large number of my errors in html (I assume that's what you're using) come from missing brackets, symbols and misspelled words.
