It seems that the attached email body is stripped, so we can not check the email text.

In case you need a tracking pixel on the Thank You page of your form, please follow the next support forum thread to find out information on this:

Adding Adwords Conversion Tracking to the Thank You page

If you need any further assistance, please let us know.

I'm sorry, I guess I wasn't very clear. What they want is to add the included code to the "submit/contact" button on one of the forms so it's trackable by Adwords. The code, again, is this:

onDISABLEDclick="ga('send', 'event', { eventCategory: 'Quote', eventAction: 'Click'});"

Hopefully that clears it up. What do I need to do? Thanks.

You will need to use a form source code on your page to be able to add the custom javascript.

Add you custom javascript to the button with 'form-submit-button' class, and use the modified code on your web page.

Thank you.
