How do I correctly use Macro Builder to have a form auto select a TAB depending on a value selected in a combo box?

Question

I am working in access 2013 to update a database first created in Access 2003. It has been saved as an accdb but I have the same problem in earlier versions.
I have a Tab Control subform in my MainDataEntry form which has 5 different tabs. Each Tab has its own set of text boxes and combo boxes for data entry. At the top of the MainDataEntry form there is a Text box [Text393], which has a drop down with
the 5 TAB names, [Mobile Device],[Computer],[Loose Media],[Network] and [Original Device]. When I select one of these values in the Text box, I would like to automatically set focus on the first Textbox or ComboBox inside the corresponding TAB.
I have tried to do this using the MacroBuilder inside the "After Update" Property for the Text or Combo box that is on the MainDataEntry Form using "If" and "Else If" statements for the "GoToControl" action, however
I seem to be able to only get one Tab to work. I have tried several different variations of this, putting the If statement first and the action argument second...putting all arguments inside a group, or not grouped....nothing seems to work. What am I
doing wrong?
EXAMPLE:
If [Text393]=[Mobile Device] Then
    GoToControl
         Control Name   Combo471
Else If [Text393]=[Computer] Then
    GoToControl
Control Name   Bios_Date
Else If [Text393]=[Loose Media] Then
    GoToControl
         Control Name   Combo659
Else If [Text393]=[Network] Then
    GoToControl
         Control Name   User Name
Else If [Text393]=[Original Device] Then
    GoToControl
         Control Name   Combo814
End If

Answer 1

In the Macro Builder's AfterUpdate event for [Text393]:
GoTo Control
  Control Name =Forms!MainDataEntry.Controls(Text393.Value).Name
To ensure that the first control on each tab receives the focus, set that control's Tab Index property to zero (0).
