I have joined two tables(table1 & employeeinfo) and when i enter the code below, i retrieve the desired results, but now i am trying to remove all rows that have a blank value for the employee name since those staff no longer work for the agency.  Employeename is retrieved from the employeeinfo table.  

I thought all i had to do is Where table1.lastuser Is Not Null AND EmployeeName Is NOT Null, but realized that means both those fields have to be Null to be removed.    

SELECT table1.LastUser, [LAST_NAME] & " " & [FIRST_NAME] AS EmployeeName, employeeinfo.REGION, employeeinfo.DEPTNAME, employeeinfo.JOBTITLE
FROM employeeinfo RIGHT JOIN table1 ON employeeinfo.LOGNAME=table1.LastUser
WHERE (((table1.LastUser) Is Not Null));

I have attached what the query looks like now.  The highlighted fields are the only ones i want to retain.

You can use:

IIf(Trim([LAST_NAME] & " " & [FIRST_NAME]) = "", Null, Trim([LAST_NAME] & " " & [FIRST_NAME])) AS EmployeeName,

Then you filter for EmployeeName Is Null.
