setfocus on an textbox

[white_flag]

hello I have an textbox "nume" and I like to be focuse, the cursour to stay there till something will fill the textbox:

I put this code but it is not working:

Private Sub nume_AfterUpdate()
    If IsNull(Len(Me.nume)) Then
        Me!nume.SetFocus 'this part it is not working
    Else
        Me.Dirty = False
        DoEvents
        Me!List36.RowSource = Me!List36.RowSource
 
        ReadOnly_Click
        Me.List36.Selected(Me.List36.ListCount - 1) = True
        Me![nume] = Me![nume]
    End If
End Sub

Private Sub nume_BeforeUpdate(Cancel As Integer)
    If IsNull(Len(Me.nume)) Then Cancel = True
   
End Sub
