Concatonating

Hello, my first post on this site. I have a small procedure in VBA that populates the Row Source of a Combo box in Access 2002.
It works fine, except it is not concatonating the Last name, and First name like I want. I am looking for "Doe, John". What I get is "Doe". Can someone tell me what I'm doing wrong? I have pasted it into the SQL view of a query, and it works. Just not in code. Any help is appreciated since this is driving me mad!

Code:

Private Sub Form_Load()
Dim strActiveSQL As String

If IsNull(Me!AssignedTech.Value) Then
strActiveSQL = "SELECT [EmployeeID], [EmployeeLastName]" & ", " & "[EmployeeFirstName] AS [EmployeeFullName] FROM tblUsers " & _
"WHERE Active = True ORDER BY EmployeeLastName, EmployeeFirstName;"
Else
strActiveSQL = "SELECT [EmployeeID], [EmployeeLastName]" & ", " & "[EmployeeFirstName] AS [EmployeeFullName] FROM tblUsers " & _
"ORDER BY EmployeeLastName, EmployeeFirstName;"
End If

Me!EmployeeName.RowSource = strActiveSQL

End Sub

A THOUSAND THANK YOU's!!!!!!!!! YOU ROCK! That's been driving me crazy all day!

I get rusty on this stuff. I don't do it very often.

Again....Thanks!
