Need iframe help

I’m working on my friend’s website that was design by someone else and the way it was design that top header is flash including the menu and rest is html. i want to use iframe so the top flash stays when the link changes but when i opened the flash i found the action script like below on link.

[COLOR=red]onClipEvent (load) {[/COLOR]
[COLOR=red]num = 3;[/COLOR]
[COLOR=red]txt_var = “index-2.html”;[/COLOR]
[COLOR=red]}[/COLOR]

and i don’t know where or how to add action script for iframe. i already have html part of script on my html page.

[COLOR=red]<iframe src=“index-2.html” name=“frame” width=“951” marginwidth=“0” height=“480” marginheight=“0” scrolling=“No” frameborder=“0” class=“style1” id=“frame” style=“border:none;” border=“0”> </iframe>[/COLOR]

so overall i need help where to or how to modify flash script to make the link work with iframe.
