Hey hey hey.

I was gonna have a fiddle with this tutorial [http://www.kirupa.com/developer/actionscript/tween.htm](http://www.kirupa.com/developer/actionscript/tween.htm)  
so I downloaded, unzipped, saved and published it. I didn’t have a chance to fiddle with anything and it’s already broken! I get this:

**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 ideas why guys? Cheers in advance.
