Load URL in other frame in a frameset?

Can you set the button action to load the URL in a different frame in a frameset? I tried _parent setting but it opens in a new window. I have a frame on the left side and one on top for a banner area. I want the movie in the side frame to load pages in the main or below the banner frame:) I appreciate any help thank you !!!

all you need to do is name the frame (something like “main” or “content”) and set this as the target, instead of blank or top or whatever
