Problem passing a variable to a button inside a movieclip

Hello,

I have list that is generated from a database that when click it calls a seperate movieclip in the library called comments and loads data from the database in it. I the movieclip i have buttons that I am trying to pass the data to but it doesnt seem to be working.

here is my actionscript:

getReleaseInfo_Result = function (releasesID,track1url,track2url,track3url,track4url) {

_root.container.attachMovie(“comments”, “comments”, 100);
_root.container.comments._x = 325;
_root.container.comments._y = 150;
_root.container.comments.track1.text = releasesID.getItemAt(0).track1
var track1url = releasesID.getItemAt(0).track1url
_root.container.comments.track1url.text = track1url
trace(track1url);
};

Track1url is the variable I am trying to pass to use it in the on press fuction below.

on (press) {
_root.splayer.doPlay(track1url);
trace(track1url);
}

Can anyone steer me in the right direction.

thanks,

chad
