frame DOM ?

I have 2 frames.  One is called "side" the other is called "main".  What
i have is this:  In main.  There is a form text box.  And in side there
are links.  I want it to put text into the text box in "main" when i
mouseover the links in "side"

I normally do it like this when it is single frame.
onclick="window.document.forms[0].elements[1].value='text';"

But i want it to go in the other frame.  How would i do this?

Thanks for your time
