First question, have you got a test bench? Have you tried it in a simulator? This is the way to test and debug your design 

 

Secondly, you cannot have counters in asynchronous processes. If the conditions to increase the count are meet, you're expecting the circuit to increment the count an infinite number of times in zero time. Counters have to be in synchronous processes.
