/********************************************************************

This is my code implimenting a washer machine in Verilog (code C)

This project is suppose to take a payment in increments of 25 cents and

be able to do a basic (50cents), normal (75cents), and heavy (1dollar) wash loads

while the lid is closed. everything seems to work except for one thing.

The payment case or my count isnt working. It doesn not increment and i dont know why.

please help. I NEED HELP ONLY WITH THE BUG IN MY PAYMENT CASE OR COUNT.
