GridView Delete Function

This is killing me. I've searched the forums for hours and can't find the answer. My SQLDataSource is working fine except when I want to delete. I've allowed the delete function to be shown on the gridview. This is my SQLDataSource: <asp:SqlDataSource ID="IndexDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:IndexConnectionString %>"
SelectCommand="SELECT *
FROM [Index]
WHERE (Type LIKE '%' + @SearchText2 + '%')
OR (Product LIKE '%' + @SearchText2 + '%')
OR (Version LIKE '%' + @SearchText2 + '%')
OR (Binder LIKE '%' + @SearchText2 + '%')
OR (Language LIKE '%' + @SearchText2 + '%')
OR (CDName LIKE '%' + @SearchText2 + '%')
OR (Details LIKE '%' + @SearchText2 + '%')
OR (ISOLink LIKE '%' + @SearchText2 + '%')"
DeleteCommand="DELETE FROM [Index] WHERE [ID] = @original_ID"
UpdateCommand="UPDATE [Index] SET Type = @Type, Product = @Product , Version = @Version, Binder = @Binder, Language = @Language, CDName = @CDName, Details = @Details, ISOLink = @ISOLink WHERE ID = @ID">
<SelectParameters>
<asp:ControlParameter Name="SearchText2" Type="String" ControlID="SearchText2" PropertyName="Text" ConvertEmptyStringToNull="False" />
</SelectParameters>
<DeleteParameters>
<asp:Parameter Name="original_ID" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="Type" />
<asp:Parameter Name="Product" />
<asp:Parameter Name="Version" />
<asp:Parameter Name="Binder" />
<asp:Parameter Name="Language" />
<asp:Parameter Name="CDName" />
<asp:Parameter Name="Details" />
<asp:Parameter Name="ISOLink" />
</UpdateParameters>

</asp:SqlDataSource>

 
 It doesn't give me an error if I click delete but it doesn't delete the record. I've tried changing the DeleteParameter to <asp:Parameter Name="ID" Type="Int32" /> but it gives me the error "Must declare the scaler variable of '@ID'"... I saw in this post http://forums.asp.net/p/1077738/1587043.aspx#1587043 that the answer was that "The variable you have declared in the definition of the proc is
different from the variable you are using in the WHERE clause." when they are both the same. Thanks for any help.
