*******SPECIFIED CAST IS NOT VALID

I'm new to .net and this doesn't make any sense to me.  Thanks for any help.

list box properties-
MultiColumn = false
SelectionMode = MultipleSimple

It's populated from a char(2) field from SQL Server

Hi FatalErr,

Is Me.lstAidCode a ListBox by any chance? If so, try this....

   Private Function CountyCodeSQL() As String

        Dim str As String
        With Me.lstAidCode
            If .SelectedItems.Count > 0 Then
                For i As Integer In .SelectedIndices
                    str = str & ", '" & .Items(i) & "'"
                Next
            End If
        End With
        CountyCodeSQL = str

    End Function

Regards,

Wayne

Sorry, the function should be this....

   Private Function CountyCodeSQL() As String

        Dim str As String
        With Me.lstAidCode
            If .SelectedItems.Count > 0 Then
                For Each i As Integer In .SelectedIndices
                    str = str & ", '" & .Items(i) & "'"
                Next
            End If
        End With
        CountyCodeSQL = str

    End Function

ListViewItems are objects in a ListView, not a ListBox, hence the error you received.
