Why is the DLOOKP function not working on the 'Questions" tab?

I am using this dlookup function on all the tabs, on the upper right hand corner to pull the first incident title.
However, on the "Questions" tab is is giving me an error.

Here is the dlookup function I am using:
=DLookUp("[INCIDENT TITLE:]", "1-Incident-tbl", "[ Incident_ID] = 1")

What is going wrong?

Do you really have a colon in your field name?

"[INCIDENT TITLE:]"

Or a leading space?

I learned after developing the application I should not use colon in field names.
