Can I make a conditional constraint?
I have a required field to record M.E.N. Resistance in Ohms.
I also have another two optional fields for Bank1 resistance and Bank2 resistance (Ohms).
Condition is M.E.N. cannot be greater than Bank1 or Bank2.
When Bank1 and/or Bank2 is empty, entering any value in M.E.N. will obviously be greater than Bank1 and/or Bank2.
Can I put an IF statement in the Constraint column?
