Validation: allow only if first fields is empty

in Calculation Engine (Define Fields)

Featured Replies

Howdy all:

I am trying to get filemaker to validate a set of fields:

Reason1

Reason2

If reason1 is empty, then reason 2 should have something in it, but both can not be empty when the user exits the record entry. Any thoughts on that?

Thanks in advance for your help.

Validate both fields with IsEmpty(Reason1) xor IsEmpty(Reason2), meaning either field, but not both, can be empty.

Deselect 'Validate only if field has been modified' for both.

Note that this will fail if both fields have data. If that is an option, then use not (IsEmpty(Reason1) and IsEmpty(Reason2)).
