I really appreciate you taking the time to respond and add an answer.  But no matter how many times I try to search for an answer, your response keeps coming up as the "best answer". Only challenge is that you wrote your answer in a way that is very difficult for a newbie to QB to decipher.  I have spent hours trying to follow your notes and cannot seem to figure out why using your formula my payments are adding to my balance and not decreasing. Could you possibly create an answer that the average newbie can decipher? Thanks so much!!!
