suppress group footer if group header is suppressed

Update on this problem.

I am trying to suppress a group footer instance if the current value of the group field is zero.
I thought by binding the groupfooter tag to the groupfield and then checking the GetCurrentColumnValue in the BeforPrint event of the group footer (using the groupfooter tag to get the column name) I could do it. However, when I put a stop in the GroupFooter BeforePrint event, the value of the tag is empty, i.e., "".

Below is the code I used to bind the groupfooter tag to the group field:

Dim GroupFooterBinding As XRBinding
GroupFooterBinding = New XRBinding("Tag", inDataSource, GroupList(k).FieldName)
Report.Bands(GroupFooter).DataBindings.Add(GroupFooterBinding)

Here is the BeforePrint event handler to suppress the groupfooter.

Private Sub BeforePrintGroupFooter(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintEventArgs)
        If CType(sender, GroupFooterBand).Report.GetCurrentColumnValue(CType(sender, GroupFooterBand).Tag.ToString) = "0" Then
            e.Cancel = True
        End If
 End Sub

I assume it is possible to bind to a group footer tag and then examine the value at a later date.

What am I missing?

Thanks.
