title: Add a css class to <p> tags if error condition is TRUE
body: <p>Setting up an error condition so that when the condition is true a css class will be added.</p>
  
  <p>For example, when the condition is FALSE <code>&lt;p&gt;&lt;/p&gt;</code> do nothing, if TRUE add a class. <code>&lt;p class="error"&gt;&lt;/p&gt;</code>.</p>
  
  <p>Here is the jquery I am using to add the calls but it not working.</p>
