ActionScript 2 | Masking

Hi everyone…
I’ve just made an OO menu in flash mx2k4 however… i need to mask it… as when i import it(loadMovie into a container in another movie), the thing becomes bigger than the stage width etc… which i don’t want.
http://www.bikkies.f2s.com/page.htm shows the old and hacky menu fitting into constraints as i want it to, however the new one requires a mask to make it fit into the area shown
I’m not sure how (or where) to apply this to make it work, so if someone could show me how to dynamically create a mask that can apply to my situation it’d be very helpful. And I have checked out the tutorial on scriptable masking, and have had no sucess thus far.

please see the attachment for my example… everything is scripted… (so i think the mask can only be scripted too)

thanks a lot for your help
Chris

here ya go!
you need one mask for each menu.

Thanks…
You’re a star…and that is most helpful to me…
