ActionScript 2.0 :: Take The Code In The "random" Layer, And Create A Function?

Could someone take a look at this fla and tell me how I can take the code in the "random" layer, and create a function, much like the startMove function at the bottom that stops the movement of the bars moving around and moves them back to their initial _x positioning. The bars that get moved around are in the "trend bars" layer. There seem to be a lot of ways to do this but since there are only going to be 6 bars, I would be open to a funciton that hard coded the initial target _x positioning in for each bar and then stopping the movement
