Hi expert, I have a trouble. In PO, i created 3 fields to identify quantity of 3 locations. and i usder workflow to sum these. with formula is after field edit: {id field 1}+{id field 2} + {id field 3}. but result is not correct. any one can help me?

It is concatenating strings 10+20+10 = 102010. You need to convert each value to a numeric type to get 40.

Type is interger
