Move in opposite direction of mouse

HEY, I’M NEW TO FLASH KIT!!!
Unfortunately I need some help URGENTLY!!!

I want to make a movieclip [COLOR=red]MOVE IN THE OPPOSITE DIRECTION OF THE MOUSE [/COLOR] according to the parameters of a smaller version of the same movieclip.

So, I want it so that if the mouse is at the egde of the small movieclip then that area of the larger clip can be seen through a [COLOR=blue]a scripted mask that follows the mouse[/COLOR]

I Already Scripted the Mask- Don’t worry

I want it to look kinda like the attached file but I want the lrg clip to stop once you get to the egdes of the small clip.

This would help alot.

I kinda have a deadline

Thanks!!!
