Error when i add splitter bar

Hello all,

i am working on spillter bar in asp.net.

For that i am using this link.

http://www.codeproject.com/KB/webforms/VwdCmsSplitterBar.aspx?fid=411085&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=76

I did all things explain here in this link. My application is working quite fine in my local machine. But when i uploaded it to my server it is giving me error.

When i tried to access it from outside of server means from any other machine, it is giving me Configuration error i.e.,

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

And when i logged in into server by using Remote Connection and tried there to access website as a local machine , it is giving me an error like;
