I know the code to put in the left frame so it will open up in the right frame:

<a href="pagelinkedto.html" target="rightside">

But whenever I put it in the left frame (changing the URL of course) it opens a new window. Please help!

Can I have a URL of your website?

To see it click here. (http://www.chocolate-kitty.dot.nu)

I found your problem. Your frame names don't match. Inside your source on your website, the frame names that you have given are "ANamethatUsersDontHave" and "adpage". You have to pick the frame that you want targetted and put it into your links.

<a href="YOUR URL" target="YOUR CORRECT FRAME NAME">agfagafa</a>

I'm too lazy to e-mail this to you. Please check back on the forum when you have the time...
