Working with an if statement, could use some help, please

Hello there,

I have a movie clip called mover that I can ease up and down with buttons, and some action script to alpha a box if the top of the mover clip goes above the top of a stopper clip.

Its an if statement and sadly only runs once. I made a controller movieclip which I thought would trigger the if statement each time the onEnterFrame was crossed… but sadly it doesnt work.

I have sreached and read alot and am just stumpped, and yes a novice at AS…

I have attached a fla below, I cleaned it up alot so it should be pretty straight forward if someone to look through. If someone is willing to take a look at it, that would be great. Or point me in a different direction.

Thanks so much,

Dale
