I need help finding an error

1

the .fla can be downloaded here, use the mouse to move the purple square around, click the colored squares to pick them up. the blue and green squares don’t have some of the code that the red square has. just ignore the small purple square and the big brown square. click the red square to pick it up, click it again to select it, click one of the other squares to collect it, and click it again. the red square is supposed to move to a certain point, stop, move to the center of the screen, and delete itself. that’s not happening and i can’t figure out why.
