My problem is simple I think, but I can't find the right solution:

I made a button in Flash. I imported that button (.swf) in a html file with 2 frames.
The button is in frame 'left'. When I click the button, I want the file that it is linked to (named: 'green.html'), to open in the frame named 'right'. But I don't know the right code to follow the 'green.html' code between the brackets. The code in the button I already have (but that opens the file in the same frame as the button) is:

on (release) {
getURL('green.html');
}
