My form was working fine in the past, and now it is not. I'm not sure why. I've been through the code several times and have yet to find anything. The form posts with the general error that is in the code. So, something is breaking, but I'm not sure what.

Form code:

<form action="contact_process.php" method="post" name="contact">
	<table width="95%" border="0" align="center" cellpadding="2" cellspacing="2">
      <tr>
        <td width="14%" class="text"><strong>Name:</strong></td>

        </label></td>
      </tr>
      <tr>

Looks like you don't have a conditional to trigger the mail to be sent. Try replacing the last 24 lines of contact_process.php with this:

// If everything is okay, send the message
			if ($name && $email && $city && $state && $phone && $occupation && $reason && $interest && $timeframe && $comments)
			{
				echo "<br><p class='blackheader'>Thank you for your interest in our Caddy Card distributorship opportunity. Someone will be in contact with you shortly.<br>";
			$body = "The following has been submitted from the Caddy Card Biz website:\nName: $name\nEmail: $email\nCity: $city\nState: $state\nPhone: $phone\nOccupation: $occupation\nReason: $reason\nInterest: $interest\nTimeframe: $timeframe\nQuestions/Comments: $comments";
				mail ($to, $subject, $body, $headers);
			} else { // One	 form element was not filled out properly.
				echo "<p class='blackheader'>Please go back and fill out the form again.</p>";
			}
			?>
