Using a text field as Lookup

[Alan_Larsen]

Help! Text functions don’t seem to work with a lookup field - FIND always returns 0, SUBSTITUTE always returns “#ERROR!” and so on…

I agree this isn’t useful or expected behavior.

However there is a workaround—append (or prepend) an empty string to your field reference and it will work.

This will produce an error: LEFT({Lookup Field},5)
This will work as expected: LEFT({Lookup Field}&"",5)

This will work with all string/text functions including FIND, SUBSTITUTE, LEFT, RIGHT, etc

That’s a great workaround - thanks so much!
