Hello there!
I’m after some guidance on how to set-up my Facebook Pixel for form submission clicks.
I’ve managed to set-up my Facebook Pixel and have used the woo commerce add on to configure it for my store.
What I would like to do is track when people click a button to submit a form. I would like to be able to do this for multiple buttons and forms.

This is the instructions given on the Facebook Events Manager page, but I am at a loss. Is this code meant to be stored in my functions.php file? Or elsewhere?
If anyone has any guidance or direction it would be greatly appreciated.
Thanks in advance!
