How can I get an onPress from a button inside a scrollPane?

programming flash
1

I have the following structure set up from the top down - one inside the other on the stage. All instance names have been assigned properly:

card1_btn: a MovieClip that contains a scrollPane
scrollPane: the name of the scrollPane MovieClip
buttons1_mc: a MovieClip attached to scrollPane in the contentPath Parameter
card1_button1: a button (MovieClip) which is the first of a row of links

I’ve been trying various combinations of this from the main timeline to get a response when I fire the link (card1_button1) but nothing works. This is the longest version with everything in the path:

 Code:
 card1_btn.scrollPane.contentPath.buttons1_mc.card1_button1.onPress = function () {    
trace("link 1")

}
Of course I can do this the easy way and just put this inside buttons1_mc and it works perfectly:

 Code:
 card1_button1.onRelease = function() {
     trace("link 1")

}
I’m just trying to be a good little programmer and put all my code on the main timeline

Thanks
