How to I pass an array?

How can I pass an array when the user clicks a button back to the main pane? The displayPictures() is just for debugging but I do need to pass the picArray so the movieclip can load the images. Any ideas?

on the main pane I put these:



var pictures = new Array();

function setPictures(picArray){
   	  this.pictures = picArray;
}

function displayPictures() {
	 for (i=0; i < this.pictures; i++) {
	        trace("PICTURES:" + this.pictures*); 
	 }
}

Then on the button I put this in the onPress event:



on(press) {
     _root.setPictures(pArray);
     _root.displayPictures();
}
