External SWF Button Issue

I'm using Flash CS5 and Action Script 2.0

My site is in 100% Flash. I have a main swf file that is the base of my site. The content of the site is loaded externally. The content is also a swf file. The content swf file has a button in it that on release will get a URL.

The issue is, I can't get it to open in the same browser. The only way I can get it to work is if I have it open in a new browser. Not what I want.

This is the code I am using.

on(release){
getURL("http://www.site.com", "_self");
}

But it won't go anywhere when released. The only way it works is if I change _self to _blank. Again, I don't want a new browser to open.

Thanks!

Resolved: I took the code of the button itself and created the button action as a function on the main timeline.
