I\'ve decided to change my team to the Cable Forum CPDN team since I post on the forum a lot, but my credit hasn\'t added onto the total credit yet, and my name is shown up in the member list. Does my existing credit add onto the total of my new team or does it stay on my last team?

It stays with the team you were with when you earned it. So your new team will only get new credits, not the old ones.
