Using Dynamic Population in Gravity Forms

I had a need on a WordPress forms using Gravity Forms to determine which button was clicked to get to the form.  Dynamic Population allowed that a query string could be added to the URL of the button and pass a parameter into the form.  This is down by using a hidden field to store the query string and dynamically populate the field value.

The URL would be something like:

http://siteurl.com/form-url/?your_parameter=value
