Add Google Analytics click event tracking code in the submit button

I need a solution to “bridge” my conversation (Google Goals) through sales pipeline. Currently, I am running two ad campaigns to a Landing page, called "Audientivity". I set up a Google Analytics Goal to track the funnel whenever someone goes from my "ad" to the "landing page" and then to the "schedule a demo" page, but I still need to create a click event goal for "schedule a demo" page and so I know who who clicked on the button to actually submit a form. The important thing about the form is that it is a Netsuite template form (I use Netsuite for my CRM), so when a user clicks the button, it pushes the form fields to Netsuite. So the button must still be able to have that function, but also the click event. Attached is the HTML for the form and button. the only part of the HTML that needs work from you is the button area. Thanks. Below are some supporting links and code that you may be able to use. In the Submit button we need to add the event tag: [login to view URL] [login to view URL] This is the code that needs to be updated based on our button code and then it will come as an event in the analaytics: onClick="ga('send', 'event', { eventCategory: 'order_now', eventAction: 'button_click', eventLabel: 'section_intro'}) example: <a href="/order-now" class="custom-button-black" onClick="ga('send', 'event', { eventCategory: 'order_now', eventAction: 'button_click', eventLabel: 'section_intro'});" >Order Now</a>
