Trying to write selected values from a listbox to a table

I have the following code in an afterupdate event of a form.  I've tried my best to construct it but am not sure it is right. Three things...

1) Will the code work?
2)  Why am I getting a "Else without If" when I try to compile?
3)  Is the after update event of the form the right place for this?

Here's my code so far:

Private Sub Form_AfterUpdate()

    Dim RS As DAO.Recordset
    Dim varitem As Variant
    
    Set RS = CurrentDb.OpenRecordset("tblSelectedLoadIDs")
    
    If DCount("[DASContractNumber]", "tblSelectedLoadIDs", "[DASContractNumber] = " & Forms!frmBillOfLadingSelector!txtDASContractNumber) > 0 Then
        With RS
        For Each varitem In listLoadIDs.ItemsSelected
        RS.Edit
        RS!SelectedLoadID = Me.listLoadIDs.Column(2)
        RS!DASContractNumber = Me.txtDASContractNumber
        RS.Update
    Else
        With RS
        For Each varitem In listLoadIDs.ItemsSelected
        RS.AddNew
        RS!DASContractNumber = Me.txtDASContractNumber
        RS!SelectedLoadID = Me.listLoadIDs.Column(2)
        RS.Update
        End With
    End If


    RS.Close
    Set RS = Nothing

End Sub
