Google Adwords form tracking

I have been given some code by google to track when someone clicks on an google ad and then fills in a form, not sure what the [emailVariable] is, (please refer to the code below) thought i could inspect the page to find but dont seem to be having any luck

<script> var ecData = { "email": '[emailVariable]', }; window.dataLayer = window.dataLayer || []; window.dataLayer.push({ 'event': 'formSubmit', 'ecData': ecData }); </script>
// Please replace [emailVariable] with the variable that tracks the email from the form and add the customized code on the back end of the thank you page//
