Cannot get reCaptcha to verify on my site

[ry...@rkcomputersystems.com]

Hello,

I have an existing contact form I am trying to add recaptcha to but am having trouble authenticating the form. Here is my code:

<?php

$title = "Contact Us";

$keywords = '';

$description = '';

include 'includes/header.inc.php';

?>

<div id="contact">

<?

// Attention! Please read the following.

// It is important you do not edit pieces of code that aren't tagged as a configurable options identified by the following:

        $email    = ''; 

        $phone    = ''; //Remove the // tags and this text to active phone number.

        $comments = '';

I am using recaptcha_challenge_field and recaptcha_response_field for the verification. With the current code above, the form will only submit when the number 8 is entered into the captcha field. This is because I am using 

else if(trim($response) != '8') {$error = '<div class="error_message">Attention! The captcha you entered is incorrect.</div>';}

Any ideas on how I can verify this captcha using the form above?

Thanks,

Ryan
