 * I am developing a site and I am using my very basic knowledge of php to try and
   conquer Mount Everest. I was never supposed to be the developer, only the designer,
   and I am now in the deep end. Any help on this will greatly be appreciated…
 * I am trying to dynamically populate a field using Gravity Forms, and the support
   there is GREAT, but takes time and I am running out of time, so I am trying anything
   at the moment.
 * The function to dynamically populate a field :
 *     ```
       add_filter('gform_field_value_your_parameter', 'my_custom_population_function');
       function my_custom_population_function($value){
           return 'boom!';
       }
       ```
   
 * This works and I get boom! in my field… Now I am calling the function like this:
 *     ```
       $unique_id = 'WP11003';
       my_custom_population_function($unique_id);'
   
       And here is the customised function :
       ```
   
 * add_filter(‘gform_field_value_your_parameter’, ‘my_custom_population_function’);
   
   function my_custom_population_function($value){ echo $value; return $value; }`
 * Now what happens is that I get the correct value echoed, but nothing is returned
   to the form. If I put :
 *     ```
       $$test = 'WP11013';
       return $test;
       ```
   
 * Then it works, but as soon as I try to return the value that was passed to this
   function it doesn’t work at all.
 * I know this is very hard based on the snippet of code I gave, but any help will
   be really appreciated.
 * Thanks in advance!
