AutoComplete Extender Doesn't Work...

I need help regarding a AutoComplete Extender that I am using. I Added an AutoComplete Extender on my ASP.NET application, then wrote the code for the webservice. It doesn't seem to work. The webservice works perfectly because I debugged it and got what I needed from it. But it doesn't display the suggested information when I type into the textbox. Can someone come to my aid....
 Below is the code:
