Accessing the DataList footer in ASP.NET

[amiga500]

Hello,

I have a DataList that displays the item information and total price
of each time but I want to add a footer with a complete subtotal. I am
using ASP.NET (VB) however I don't know how to call a footer in my
code, below is the code I have added:

CType(e.Item.FindControl("lblFooterTotal"), Label).Text =
CompleteTotal

However I get this "Object reference not set to an instance of an
object." because it cannot find the footer. Here is the HTML code:

<FooterTemplate>
<asp:Label ID ="lblCompleteTotal" runat =
"server">Total:</asp:Label>
<asp:Label ID="lblFooterTotal" runat="server"
Text="0"></asp:Label>
</FooterTemplate>

Can someone please help me in this regard? Thanks in advance.
