Constrain x movement

‘’’ thanx both for explaining that you can’t declare multiple event handlers. ‘’’

… perhaps if i explain my objectives better than before…

i want to move one clip by the x (<->) movement of the mouse.
and constrain the movement of that clip, to the x (<->width) of another clip.

‘’’ silly of me not to make that clear in the first place,
tired, not even sure what i’m doing myself, but thanx guys ‘’’ James
