Need help having a movieclip button call/get a .swf file

Hi all-

I’m making a site and having some trouble here. I have made a moveiclip button and now all I want to be able to do is have it load a .swf file.

I have a master.swf that will call the mainmenu.swf when it loads everything.

So basically the mainmenu will be loaded into the master then work from there. I know this is something so freakin’ easy but I can’t figure out how to get the button to “call” the .swf file.

Here’s the code I have so far that allows for the button to do it’s magic:

**this.button_mc.onRollOver = function() {

this.button_mc.onRollOut = function() {


I have already tried this a.s.::
this.button_mc.onRelease = function(){

And it’s still not working. It didn’t get the .swf file

Any help is greatly appreciated as I am totally stuck here.

Thanks in advance.
