CAPTCHA server validation is not working
I have a server validation on my contact form for my CAPTCHA. When the submit button is pressed, I'm using a validation type of Like Entry ($_SESSION['captcha_Security_Code_1']), and "is the same as" ((isset($_POST["Security_Code_1"]))?$_POST["Security_Code_1"]:"").
It's allowing the form to be submitted without the CAPTCHA. I've attached the form. Thank you.
