 * Paste the script from this gist into the script code editor and hit Save.
 * From the Publish menu, select Deploy as web app…
 * Choose to execute the app as yourself, and allow Anyone, even anonymous to execute the script. (Note, depending on your Google Apps instance, this option may not be available. You will need to contact your Google Apps administrator, or else use a Gmail account.) Now click Deploy. You may be asked to review permissions now.
 * The URL that you get will be the webhook that you can use in your elementor form, You can test this webhook in your browser first by pasting it. It will say "Yepp this is the webhook URL, request received".

  var message = "A new subbmition has been recived via " + data['form_name'] + " form and inserted into your Google sheet at: " + url;
	MailApp.sendEmail( emailAddress, subject, message, {

}

How would I go about adding the form values to an existing sheet with existing headers? Essentially, I'd looking to keep one sheet with an ongoing list of the form values that gets updated on a new line, instead of a new sheet.

Still working?
