Allow carry over rules: 1. If allow Carry Over = 0, we always SET carry over = 0 2. If <> 0, we cap the carry over to this amount e.g. If Balance = 100, Allow Carry over = 0, New B/F = 0 If Balance = 100, Allow Carry over = 80, New B/F = 80 If Balance = 100, Allow Carry over = 110, New B/F = 100 If Balance = -16, Allow Carry over = -5, New B/F = -5 as -16 smaller than -5 |
