Using the Tween Class Problem

Anyone have problems with the source file for the “Using the Tween Class” tutorial?

I get this in my output window when I test movie.

Error Scene=Scene 1, layer=actions, frame=1:Line 5: There is no property with the name ‘onMotionFinished’.
xScaleT.onMotionFinished = function() {

Error Scene=Scene 1, layer=actions, frame=1:Line 8: There is no property with the name ‘onMotionFinished’.
xPosT.onMotionFinished = function() {

Total ActionScript Errors: 2 Reported Errors: 2

Any clues?
