Transitions between External SWFs - Voetsjoeba Tutorial

hi there, im pretty new when it comes ta flash so please forgive me.

I have followed through this tutorial:

And I can get it to work when the buttons are on the main scene, but I want my buttons to be in a movie clip within the scene. I then follow the tutorial again but I get the following message:

Scene=Scene 1, Layer=actions new, Frame=3: Line 1: Operator ‘=’ must be followed by an operand
_root.currMovie = “work”;

hope that makes sense…, what Is it im doin wrong?

Thanks, keljnr.
