With regard to your template, your code is
Code:
Case Is = "Zomer/winter"
If .ShowingPlaceholderText = True Then
Set oCC = ActiveDocument.SelectContentControlsByTitle("WinterTekst").Item(1)
oCC.LockContentControl = True
oCC.Range.Text = ""
Else
For i = 1 To .DropdownListEntries.Count
If .DropdownListEntries(i).Text = .Range.Text Then
Select Case .DropdownListEntries(i).Text
Case "Kies een item."
AutoTextToCC "WinterTekst", ActiveDocument.AttachedTemplate, "TipKeuze"
Case "Enkel in de winter"
AutoTextToCC "WinterTekst", ActiveDocument.AttachedTemplate, "PrimerAnhydriet"
Case "Niet in de zomer"
AutoTextToCC "WinterTekst", ActiveDocument.AttachedTemplate, "TipZomer"
End Select
Exit For
End If
Next
End If
There is no "PrimerAnhydriet" building block, so that one is never going to work, and Case "Kies een item." is superfluous as that is the placeholder text and always produces nothing because of the other half of the IF statement.
