OnClientTabSelected undefined error

[Bill]

I am using ASP.Net 3.5 and version 2009.3.1314.35 of the Telerik tools. When I run the page, I get the attached error (look on the right hand side of the page). As you can see, the runtime js does contain that event. 

I have the following code in my html:

<code>
<telerik:RadTabStrip ID="tsCoding" runat="server" Align="Left" MultiPageID="RadMultiPage1"
                                                                                    SelectedIndex="0" OnClientTabSelected="tsCoding_OnClientTabSelected" AutoPostBack="false"
                                                                                    CausesValidation="false" ScrollButtonsPosition="Right" BackColor="Gray">
</code>

I have the following in my js:

<code>

function tsCoding_OnClientTabSelected(sender, args) {

                var tab = args.get_tab();
                if (tab.get_tabs().get_count() != 0) {
                    tab.get_tabs().getTab(0).enable();
                    tab.get_tabs().getTab(0).select();
                }
            }

</code>

When I remove the OnClientTabSelected="tsCoding_OnClientTabSelected" from the tabstrip, the page works fine. Having it in there causes the attached error.

What do I need to do to resolve the error?

Nevermind... I corrected the error. It was a js error I had in the page.
