Default FindControl in nested repeater

I keep getting a System.NullReferenceException error when I try to find a control in my nested repeater(rptProducts). I have an image button that on click I need to check to see if any checkboxes have been checked in the nested repeater, I will eventually store this information in a cookie.

Protected Sub ibHR_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ibHR.Click

        Dim rptr As Repeater
        Dim d As RepeaterItemEventArgs
        rptr = CType(d.Item.FindControl("rptProducts"), Repeater)

        Dim rc As RepeaterItemCollection = rptr.Items

        For Each Item As RepeaterItem In rc
            Dim MyCheckBox As CheckBox = CType(Item.FindControl("chkProductID"), CheckBox)

            If MyCheckBox.Checked Then
                Response.Write("ProductID = " & MyCheckBox.Attributes("ProductID") & "</br>")
            End If

        Next
        Response.End()

End Sub

I think the problem is that it can not find the repeater - because I can not access it by name anywhere in the code behind.

Any help would be appreciated. Thank you.
