I'm sure there is a simple answer to this but I can't seem to find it. I am trying to constrain an integer field to a specific length. I however don't understand how to make this happen from the popup on the xls sheet in the constraint column. I need to have one field that is exactly 19 numbers long and another that is 15. I am guessing it has to do with a layout that I am unfamiliar with or don't quite understand yet.
Any help with this would be appreciated.
