And your question is ... ?

This widget could not be displayed.
  1. Please put your code in a code block to improve visibility
  2. What else have you tried?
    1. Already debugged your Javascript code? How should this work? For instance FeatureToggle is an element, how should this be "Yes"?
  3. Put your code in
    jQuery(function(jQuery){ // Your code here});
    to be sure, it is loaded after all elements are rendered.
  4. Use jQuery to add event listeners, find and alter elements, to be sure you are cross browser compatible

is this script correct.Its not working after adding it.Also i added in here custom fields---)right click ---)configure ---)description.

please advise.Als advise if there is anyother script for the requirement

Have you tried Adrien's suggestions yet? Repeating the question is of no help, you need to think through the responses you get and respond to them with more information.
