Automatically fill values on a form by passing it in the URL

So this may be a bit advanced, but you could leverage the query string of a URL (e.g. in order to populate a default value when someone lands on a form.  To do this, follow these steps:

  1. Build your Form
  2. Add your questions
  3. If not on the page that displays all questions, click "View Questions"
  4. You will now see a label with the key that you need to pass in the URL (e.g. field_1234_5678)

  5. Simply add this URL to the query string of the URL.  For example if the URL to the form is simply add ?field_1234_5678=baseball to the end of the URL.  (
  6. This will now pre-populate the value on the form.  

You can also use this technique on a hidden field to store data from the source.

Please note this will only work on new submissions, it will be overwritten if they are editing their response.
