=IF ( FIND ( xxx gives a #VALUE! so the 'Not True' is not executed

You would normally use it like this:

=IF(ISNUMBER(FIND(...)), action_if_found, action_if_not_present)

SEARCH might be better than FIND, as it is not case-sensitive.

Hope this helps.

Thanks Pete, it works and also the solution from "ConnectionLost" (IFERROR) works perfect
