Missing last name

I was editing some areas of jotform, I am not sure what I did but when the form is filled out completely and I hit submit it is emailed to the address we set up and the subject line would look like this :

NEW JOB: Jones- Fire / smoke - Sp Whitemarsh

Now it does not show the last name on the subject line (see below) and I am not sure how to fix it so it shows like the subject line above.

NEW JOB: - Fire / smoke - Service Master Allentown

2. Click the Edit button.

3. Add the {lastName} in the Email Subject and click the Save button when you're done.

Hope that helps. Let us know if you need further assistance.
