I am trying to create an html5, jquery, webapi application and can't even get by the first page, since all of this in brand new to me.

I added the nugget package jquery ui and after install tried to use their accordion tool. I have verified via developer tools that to code.jquery.com are returning valid css and script. I coped most of the code from the jquery ui demo page.

When run, I get the following error message on the call to: $("#accordion").accordion();
Unhandled exception at line 99, column 21 in http://localhost:64779/Home/Index
0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'accordion'


Can anybody see what's wrong? Much appreciated.
