Well, I just tried something out, just for kicks, and I got this to work.
I created a Combo box and here are some of the properties I set:
Record Source Type = Value List
Row Source = "FName";"First Name";"LName";"Last Name";"EmpID";"Employee ID"
Bound Column = 1
Column Count (Listed under "Format", not "Data"

= 2
Then, in the On Change event, I put this code:
Private Sub Combo6_Change()
Me.Controls(Combo6.Column(0)).SetFocus
End Sub
I guess, all you really need to know is this:
To set the focus of a control, that you have the name of (as a string) just put:
Me.Controls(
control's name).SetFocus
I just kinda went a step beyond. Also, with the ComboBox version, you eliminate the problem of accidentally typed incorrect control names, and can choose "User Friendly" control names.
