Google reCaptcha not stopping spam

Hi Ray, you kindly helped me to properly integrate Google's reCaptcha v3 invisible challenge widget via a premier support ticket a few months back. I've been trying to do the same on another site and (I think) I copied over all the code as you had it, however the client received more than 3,000 spam emails over the weekend so I've obviously missed something!! Would you mind taking a look at this page to see what I've done wrong?

Your recaptcha code needs to be above the validation code and you have to validate the returned value from the recaptcha... and the trigger should be the same as the validation. You have the recaptcha code repeated twice (remove one) and you have it below the server validation and never validate the $recaptchaScore value returned.

I knew I was missing something... I'd overlooked the validation code from the other site. Does the attached page look OK now?

Yes that looks better. You should update line 90 to:

<?php if((isset($_POST["submit"]) || isset($_POST["submit_x"])) && isset($_POST['event'])) { // send if Mortgage or Protection Event ?>

and delete the blank line at line 59

Thanks so much for your help!
