Link to an html frame

i’m building a website where the top and bottom parts are divided by a frame. the top part houses my flash movie. my question is, can i link a button from the flash movie so that it opens a page in the bottom part of the frame? i’ve tried searching the forums but i’m still a beginner and not quite familiar with actionscript yet and so was not able to find what i’m looking for. any help would be appreciated. thanks!
