Stupid Question really:

I need to open 2 different pages into 2 different frames on clicking on a button... For the life of me I can't remeber how to do it.. I think that age is catching up with me.. (or I need more coffee)

I have 2 frames : topframe and mainframe and I currently make the topframe change on the button click .. but I need to change the information in mainframe too.

Cheers for your help.. I'll now go n book myself into the OAP home...
