Userform: Creating default text in a Textbox from the text entered in another Textbox

[gmayor]

The following code should so the trick

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    If Me.TextBox2.Text = "" Then
        Me.TextBox2.Text = Me.TextBox1.Text
    End If
    If Me.TextBox3.Text = "" Then
        Me.TextBox3.Text = Me.TextBox1.Text
    End If
End Sub

This will fill textboxes 2 and 3 on exit from textbox1 if they don't already have a value.
You may change 2 and 3 without effecting a change elsewhere.
