Hi I have a question can anyone help me out?

This is the result from a phpfile:
a0=What I am&b0=Edie Brickell&c0=Pop&d0=Sound1.swf&a1=Many men (wish death)&b1=50 Cents&c1=Rap&d1=Sound2.swf&a2=Last to know&b2=Pink&c2=Rock&d2=Sound3.swf&a3=Hardcore vibes&b3=Dune&c3=House&d3=Sound4.swf&a4=Stressed out&b4=Tribe called quest&c4=Rap&d4=Sound5.swf&

I load this into flash using:
myVars = new LoadVars();
myVars.load("http://blahblah/audio.php");

I have a dynamic textfield with an instance name called: content

What I would like to do is control the contents of this textfield.

How can I display one of the variables in this textfield? I tried several things but I just can't get it to work, so any help would be great
