Dark GDK Sprite Trouble

[gprogmary]

I am currently trying to modify a game I have done in a class by changing the sprites an variable names. That all went well but the trouble is that one of the elements of the game stopped working. The game involves box dropping down from a truck into a basket while there is a counter up on top of the screen counting down the number of boxes dropped. The counter is mini versions of the box that is supposed to decrease by one each time a box is dropped. The mini boxes do not decrease, but in the original version this element still works. What is up and can anyone help?
