Troubling destroying grid in Breakout knockoff

I started creating a pong knockoff, then it kind of elaborated into a Breakout/Arkanoid knockoff, and I seem to have everything in order except
[list]
[]the Game Over / Play Again part
[
]destroying the grid
[/list]I generate the grid through 2 for loops, and each block is assigned a unique name (block1-30 I think), I just don’t know how to dynamically hitTest each one of those blocks so they can be unloaded/taken out of the movie when the ball hits it.

Here is the .fla, can someone please help me? (the grid code is in the top frame, as well as my apparantly unsuccessful attempt at detecting collisions within it.)
