The type specified in the TypeName property of ObjectDataSource 'LeaguesODS' could not be found.

I have created a website using Visual Web Deveoper 2008 Express and SQL 2005 Express.  It is coded in C#.  The site is working fine on my local PC, but when I upload it, I get the following error message:
"The type specified in the TypeName property of ObjectDataSource 'LeaguesODS' could not be found. "  I have verified that all my files are uploaded.  Oh, and when I upload the database files, I upload them to SQL 2005 instead of SQL 2005 Express.

Here is my code for that part:
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
        DataKeyNames="LeagueID" DataSourceID="LeaguesODS" Width="150px">
        <Columns>
            <asp:HyperLinkField DataNavigateUrlFields="LeagueID"
                DataNavigateUrlFormatString="Main.aspx?LeagueID={0}"
                DataTextField="LeagueName" HeaderText="Leagues" />
        </Columns>
    </asp:GridView>
    <asp:ObjectDataSource ID="LeaguesODS" runat="server"
        OldValuesParameterFormatString="original_{0}" SelectMethod="GetLeagues"
        TypeName="LeaguesBLL"></asp:ObjectDataSource>

I have been reading around, and a lot of sites mention to put a namespace for the objectdatasource.  Where would I find what my project's namespace is?  Also, could I be getting this error because of something else??Start Free Trial
