# 4374 Locate on Non-Active Index Can Cause #601 Error When Used Right After Failed FindKey

---

I just wanted to reply to an email from someone with no works address but with a home email address. Something I've done before, No change that I know of to the segment of code that's affected - this is the line

end else if lu.Contacts.Locate('_HomeEMail', tmpEMail, [loCaseInsensitive]) then begin

The column _HomeEMail is a simple "_HomePhone" VARCHAR(25) COLLATE "ANSI_CI", with no triggers etc on it. There are NULLs and textual data in the different rows.

The result is the following error:

ElevateDB Error #601 The table Contacts is corrupt (The index page is empty).
