I am trying to query a table and find only those records that have a null in the Proj_ID field

the end of SQL statement is
WHERE (((tblLocalProject.[Proj_ID])=Nz([Proj_ID])));

what this returns is all records that don't have a null

To also cover the case of Empty String ("") as well as Null ... you can use:

WHERE Nz([tblLocalProject].[Proj_ID] , "") = ""
