John, you lead me on the right path. I never bothered to replace the uC on the breadboard ( I assumed it worked due to the functioning numbers, and the fact that it took the program) Replaced the uC, and BINGO! we have a steady functioning tube counting from 0-9.
Thank you everyone for your help! I have a few new ideas to check in the future, thanks to your suggestions. WOOHOO!
