I’m using the jquery iMask plugin found here. Here is my code: fiddle

When I run it
1) it doesn’t work correctly. The input for phone is not masked like i set it up
2) the console displays the error:

Uncaught ReferenceError: Json is not defined fiddle.jshell.net:1

What is this error and how do I fix it? Thanks

It’s not a jQuery plugin, it’s a mootools plugin.

$(document).ready(function(e) {
   $('#phone').iMask({  
     type:'fixed',  
     mask:'(999) 999-9999',  
     stripMask: false
   });
});
