I need some help about the code for swf button please.?

I'm working on a swf. I want to have the new link open in the same window after pressing a button. So I added the following code to the button. But still, this code open a new window.

on(release){

getURL("http://www.mylink.com",_self)}

I'm very new to using code in swf. All I can do is always involving with drags and drops. So any advice "for dummies" would be appreciated.
