April 20, 201015 yr Newbies I am trying to achieve the following. I have a field called Number. In this field there can be any positive integer. If the integer consists of 2 or more digits then I need to split them and sum them. This I need to repeat until I have a single digit number. For example: Number = 37 Result should be 3 + 7 = 11 -> 1 + 1 = 2 (final result) or Number 134 Result 1 + 3 + 4= 8 (final result) Which functions can I use to split numbers? Which function can I use to repeat this process until I have a single digit?
