How do I modify the code to not have to place it at the top of eh page. I have other code and design that needs to go ahead of that code.

I have some forms that are general in nature, they just return some information so that people can request a service for a company. But I would like them all to have form captcha. I kind of understand it. How much would you charge to set one of them up and then I can just add the same code to the rest of the forms, there are probably three. I know it would probably take someone about 10 minutes to do ... im just a bit clumsy with this.

Please let me know.

THanks

Jon

nevermind, i found out how to add letters, but still need to changed font.
session_start();
// Generate a random character string
function rand_str($length = 32, $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890')
{
// Length of character list
$chars_length = (strlen($chars) - 1);

// Start our string
$string = $chars{rand(0, $chars_length)};

// Generate random string
for ($i = 1; $i < $length; $i = strlen($string))
{
// Grab a random character from our list
$r = $chars{rand(0, $chars_length)};

// Make sure the same two characters don't appear next to each other
if ($r != $string{$i - 1}) $string .= $r;
}

// Return the string
return $string;
}

$text = rand_str($length = 6, $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890');
$_SESSION["vercode"] = $text;
