First Item Selected Not Showing Up In Text String

I have an unbound listbox "Needs", and in the onclick event have the following code which works great if I have more than one item selected, but if I only have one item selected, it does not put it in the text box "ServiceText".

Code:
Private Sub Needs_BeforeUpdate(Cancel As Integer)
On Error GoTo errHandler
Dim ctl As Control
Dim strStart As String, strEnd As String
Dim aryList As String
Dim varSelected As Variant

[code]....
