* Using this method, a GET parameter can be passed to the page, enabling a simple locator form to be populated and submitted dynamically.
* One use case may exist where the user submits a gravity form, and is redirected to a list of locations without needing to resubmit the simple locator form.
* This code would be placed in a page template.
