Need advice on using loadMovie

[color=#cc00cc]stop();[/color]
[color=#0000d0]this[/color].[color=#0000d0]onRelease[/color] [color=#0000ff]=[/color] [color=#006610]function[/color]color=#0000ff{[/color]
[color=#0000d0]getURL[/color]color=#0000ff[/color];
[color=#0000ff]}[/color]
This is from the “Complex Button RollOver/RollOut Effects” tutorial on this site.
I want this “movieclip button” to load a .swf movie instead of “getURL” in a main website, but I dont know how to properly use loadMovie, or if I can even use it in this situation. Will I have to convert everything into actual buttons?

I would appreciate any help you can give me on this. Thank you.
