Simple question about tween class

the code below is in index.swf, i want it to tween “_root.LabelMC” in image9.swf…where to i place the “image9.swf” in this code to tell it what i want to tween?

new Tween(_root.LabelMC, “_alpha”,Strong.easeIn,0,60,15,false);

NOTE: “image9.swf” is already loaded and" importmx.transitions…" is also in tehre and working.

(ive got other code similar to this to work across SWFs fine, i just cant work out where to put the swf label in this one)
