Trying to implement Customized web chat among users but couldn't able to integrate AJAX with the web application, I have developed so far

Hi,

I have almost developed a website using Dot net, C#, Jquery, Javascript etc. Now, for having chat among visitors, we picked the AJAX code from https://code.msdn.microsoft.com/CSASPNETAJAXWebChat-c4c9b8fe and customized it... 

When we see the demo in there, it successfully shows the chatboxes and implements the chats well... But we couldn't able to integrate it with our already built web application (Web forms and not MVC). Since we get no errors, its very hard to predict the issue clearly. Do I have to make some changes in web.config?

Getting 2 warnings alone which are as follows

<div>

Warning2The 'contract' attribute is invalid - The value 'PlayZone.Services.SessionPool' is invalid according to its datatype 'serviceContractType' - The Enumeration constraint failed. E:\Projects\PlayZoneJUNE04\PlayZone\Web.config5748PlayZone
