are you importing the Tweener class?
yes, and it's working in _root,
thou do i need to import the class on movieclips aswell i thought once should do the trick?
if you're importing it to the root that won't help with code attached to a movieclip. you shouldn't attach code to objects anyway.
attach your code to a frame:
You are correct! It was stupid to attach the code to the movieclip,
thanks for the help
