Missing field if name blank

[lewis1682]

I have a report for some labels. Here is the order and control source for the fields:
=Trim([Title] & " " & [FirstName] & " " & [LastName])


JobTitle
Company
Address1
Address2
Town
County
PostalCode

If the title and names are blank then it misses out the jobtitle. How can I fix this? if the names and title are there then it doesn't miss out any fields. Thanks.

Don't understand the error. If data is in JobTitle, why wouldn't there be title and names? Empty Title, FirstName, LastName should not prevent the JobTitle data displaying.

I would have to analyse the data and report structure. If you want to provide, follow directions at bottom of my post.
