ActionScript 2.0 :: Flash 8 : Script Crashes Flash Player?

In my "game", there are gray blocks and black blocks. The blocks are randomly placed on load (20% chance each spot will be a black, 80% of gray), and the "player", begins at (0,0).

I created two functions on the player movie clip. One, called hitTry, tests to see if the given values for a clip (x, y, width, height) will touch the given values of another clip (x, y, width, height). The other, called movePlayer, is meant to take in a variable (direct) that is the direction the player is attempting to move. Once it takes that in, it calculates the (x, y) that the player would have should he move in that direction, and plugs it in to hitTry to see if it would hit anything.

The only reason I can see for it crashing is that I use a for loop that runs the test function for each black block, testing the player's values against the values of ever black block in the game. I cannot, however, find any other way to do this.

I'm going to add the fla to the thread, seeing as it is nothing but a pet project anyways. I still would like to know the solution very much and am quite urgent about it.

P.S. I create a duplicate of the original "player" movie clip because I had problems getting the original movie clip to show over the duplicated squares. Anybody know why duplicated clips always go to the front?

P.S.2. The code for "spawning" the player and squares is in a red square out of the document boundaries called "handler". The control for the squares are also off screen, all to the left. The code for the player is in the original player movie clip, the blue circle near the other movie clips off screen.
