Use the # command to format your code with tags in the forum.
You probably want something like the following. I have only filled 1 case. Add the values to the others as appropriate. Rename the title of the dropdown field in question to match your document.

Code:
Private Sub Document_ContentControlOnExit(ByVal ContentControl As ContentControl, Cancel As Boolean)
Dim i As Long, m As Long
Dim strDetails As String
Dim oCC As ContentControl
With ContentControl
If ContentControl.ShowingPlaceholderText = False Then
If .Title = "Company" Then
Set oCC = ActiveDocument.SelectContentControlsByTitle("CountryDropDownName").Item(1)
For m = 1 To .DropdownListEntries.Count
If UCase(.DropdownListEntries(m).Text) = UCase(.Range.Text) Then
Select Case m
Case 1
'This is the prompt and should not trip the macro
strDetails = " "
oCC.DropdownListEntries.Clear
Case 2
strDetails = "Singapore"
With oCC.DropdownListEntries
.Clear
.Add "Item1", "Item1"
.Add "Item2", "Item2"
'etc
End With
Case 3
strDetails = "Singapore"
Case 4
strDetails = "Singapore"
Case 5
strDetails = "Malaysia"
Case 6
strDetails = "Thailand"
Case 7
strDetails = "Cambodia"
Case 8
strDetails = "Philippines"
Case Else
strDetails = " "
oCC.DropdownListEntries.Clear
End Select
Exit For
End If
Next
ActiveDocument.SelectContentControlsByTitle("Country").Item(1).Range.Text = strDetails
End If
End If
End With
End Sub
