hitTestObject help

[YBAB]

ok I have a thing im working on that I want to give flash the ability to register when it hits multiples of the same movie clip imbedded in another movie clip called the stage.

I know i am going to have to name the multiple movieclips different things like block1 block2 block3 ect...

but every time I try to set up a loop for this it fails, and i get massive script errors...

anyone feel like taking a quick look?
