Access 2016 VBA command button to sort not working

Question

I need help alphabetically sorting a continuous list of records on a form. Clicking button SortAZ is supposed to trigger this action.

Details: tblPatients has a list of patient names and their ID numbers. When I create a form based solely on this information, a cmd button is created and works as expected. I want to also allow the user to filter the list by any criteria (say they only remember the first name, but not the ID or last name).

frmPatients has a header above the Detail section. I can't seem to get vba to recognize the fields in the detail section. I have tried several different combinations (see commented lines) and even renaming the Detail section.

 Private Sub SortAZClick()
      Me.FilterOn = False
      Me.OrderByOn = False
     'Me.LastName.SetFocus

     'Me.OrderBy = "LastName"
     'Me.OrderByOn = True
     'Me.Detail.OrderBy = "[LastName]"
     'Me.Detail!OrderBy = "LastName"
      Me.FilterResults!OrderBy = "[LastName]"

     'Me.Form.OrderBy = "LastName"
      Me.Form.OrderByOn = True
     'me.Detail!requery
      Me.Requery
End Sub

Oh the horror!!! The problem was in the first line. Should have been Private Sub SortAZ_Click() Simply leaving out the underscore prevented it from doing ANYTHING.
