Paul, Graham
Graham appears to be correct. It seems my habit of using vbNullString in code has bitten me here. Revising my earlier Attempt2:
Code:
Sub Attempt5()
Dim oCC As ContentControl
Set oCC = ActiveDocument.ContentControls.Add(wdContentControlDropdownList, Selection.Range)
With oCC.DropdownListEntries
.Add oCC.PlaceholderText, "" 'Using vbNullString in this Attempt2 seems to have been the problem.
.Add "A", "Apples"
.Add "B", "Beets"
End With
lbl_Exit:
Exit Sub
End Sub
Appears to work as well.
