server side list box

[LeoLionHeart]

Hi I have 2 server side list boxes and 2 buttons. Selecting a item and clicking a button will transfer the item to the other list box. The transfer all works fine. However, when i click a button, before the page is posted back a little exclaimation mark comes up in the bottom left which reads:

Line:105
Char:1
Error:Object expected
Code: 0

code for that line is

<TD style="WIDTH: 650px; HEIGHT: 166px" vAlign="top" noWrap align="left" colSpan="3">

code for server button:

Private Sub btnAddB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddB.Click
        PopulateSortCombo(Me.objAddTo, Me.objRemoveFrom)
End Sub

    Public Sub PopulateSortCombo(ByRef listFrom As ListBox, ByRef listTo As ListBox)
        Dim i As Integer = listTo.Items.Count
        Dim SortListA As ArrayList
        Dim j As Integer
        Dim k As Integer

        Do While i > 0
            If listTo.Items.Item(i - 1).Selected = True Then
                listFrom.Items.Add(listTo.Items.Item(i - 1))
                listTo.Items.Remove(listTo.Items.Item(i - 1))
                'Sort list boxes
                SortListA = New ArrayList
                For j = 0 To listFrom.Items.Count - 1
                    SortListA.Add(listFrom.Items(j).Value)
                Next 'j
                SortListA.Sort()
                listFrom.Items.Clear()
                For k = 0 To SortListA.Count - 1
                    listFrom.Items.Add(SortListA.Item(k))
                Next 'k
            End If
            i -= 1
        Loop

        For i = listFrom.Items.Count - 1 To 0 Step -1
            If listFrom.Items(i).Value = "" Then
                listFrom.Items.Remove(listFrom.Items.Item(i))
            End If
        Next

        For i = listTo.Items.Count - 1 To 0 Step -1
            If listTo.Items(i).Value = "" Then
                listTo.Items.Remove(listTo.Items.Item(i))
            End If
        Next


End Sub

Any ideas - it still works but the Error alert is shown!!
