(MX) tell target path problem

This is annoying me quite severely. (full-flash site) I have an index.swf that loads a bio.swf (for example), and on this bio.swf i have numerous tellTargets. Now, when the bio.swf is loaded into the index.swf i get path errors. This is the code for one of my tellTarget buttons:

on (rollOver) {
tellTarget ("/paper") {
gotoAndPlay(“begin”);
}
}

Is there some type of path (such as _root) that i should be adding to my code? Thanks for any help everyone.

Victor.

any ideas…?
