Scriptmanager ScriptReference error in Sharepoint

[umar okeeffe]

hello,

I have been trying to include the telerik jquery libraries.
I realize by running on sharepoint I have to turn Assembly
references into the full assembly name with version info and
key number. so as a result I have changed my script references as in the code block below.
Keep in mind that this code runs in a master page, and that the page works when
I comment out the the script references. Otherwise I get the error which I posted below this
code block. Perhaps I am writing the reference incorrectly? Thanks for any help

<asp:ScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true"
        >
        <Scripts>
            <%--Needed for JavaScript IntelliSense in VS2010--%>
            <%--For VS2008 replace RadScriptManager with ScriptManager--%>
            <asp:ScriptReference Assembly="Telerik.Web.UI, version=2010.1.309.35, Culture=Neutral, PublicTokenKey=121fae78165ba3d4" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI, version=2010.1.309.35, Culture=Neutral, PublicTokenKey=121fae78165ba3d4" Name="Telerik.Web.UI.Common.jQuery.js" />

        </Scripts>
    </asp:ScriptManager>

The error is I wrote PublicTokenKey, it should be PublicKeyToken
