Find a repeater that is within another repeater - asp.net

Question

Ok so my issue is I have three repeaters. Within that repeater I have another repeater and a third one in the second. There is more in between but that's not relevant. Below the HTML is my VB code. My issue is that rptCrashPercentageAvg reutrns Nothing. How can rptCrashStatsDisplay access rptCrashPercentageAvg?
<asp:Repeater ID="rptCrashStatsDisplay" runat="server">
<ItemTemplate>
<asp:Repeater ID="rptCrashPercentage" runat="server">
<ItemTemplate>
<tr class="statsRowA">
<td class="emphasis" style="padding-left: 20px">
<%# DataBinder.Eval(Container.DataItem,"CRASH_TYPE_DESC") %>:
</td>
<td style="padding-left: 5px">
<%--background-color: <%# Iif(DataBinder.Eval(Container.DataItem,"CRASH_TYPE_PERCENT")>DataBinder.Eval(Container.DataItem,"COUNT(*)"), "red", "null") %>"--%>
<%#String.Format("{0:N1}", DataBinder.Eval(Container.DataItem, "CRASH_TYPE_PERCENT"))%>
%
</td>
<asp:Repeater ID="rptCrashPercentageAvg" runat="server">
<ItemTemplate>
<td style="padding-left: 5px">
<%#String.Format("{0:N1}", DataBinder.Eval(Container.DataItem, "AVG_VAL"))%>
%
</td>
</ItemTemplate>
</asp:Repeater>
</tr>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
Private Sub rptCrashStatsDisplay_ItemDataBound(ByVal sender As System.Object, _
ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptCrashStatsDisplay.ItemDataBound
Dim dv As DataRowView = CType(e.Item.DataItem, DataRowView)
If Not IsNothing(dv) Then
Dim rptCrashPercentage As Repeater = CType(e.Item.FindControl("rptCrashPercentage"), Repeater)
Dim view As DataView = dv.CreateChildView("statRel1")
If (view.Count > 0) Then
rptCrashPercentage.DataSource = view
rptCrashPercentage.DataBind()
End If
Dim rptCrashPercentageAvg As Repeater = CType(e.Item.FindControl("rptCrashPercentageAvg"), Repeater)
Dim viewAvg As DataView = dv.CreateChildView("statRel2")
If (viewAvg.Count > 0) Then
rptCrashPercentageAvg.DataSource = viewAvg
rptCrashPercentageAvg.DataBind()
End If
End If
End Sub

I would try making sure you're looking for it in the correct place. It'll look in your repeater's Header for the control and since it won't find it there, it'll be Nothing the first time you try and use it.
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
Dim rptCrashPercentageAvg As Repeater = CType(e.Item.FindControl("rptCrashPercentageAvg"), Repeater)
'Shouldn't be "nothing" here.
End If
Otherwise you could try a more inefficient method:
Dim rptCrashPercentageAvg As Repeater = CType(e.Item.FindControl("rptCrashPercentageAvg"), Repeater)
If rptCrashPercentageAvg IsNot Nothing Then
Dim viewAvg As DataView = dv.CreateChildView("statRel2")
If (viewAvg.Count > 0) Then
rptCrashPercentageAvg.DataSource = viewAvg
rptCrashPercentageAvg.DataBind()
End If
End If
Edit: Also, since it actually is a repeater, you shouldn't need the CType.
