Need Help With ReCaptcha

[incrediblehelp]

Not sure if anyone has used this ReCaptcha program before. I am trying to get it implemented on a simple PHP mail form:

but I keep getting this error:

http://www.kbkmarketing.com/mailer.php

Fatal error: Call to undefined function: recaptcha_check_answer() in /home/kbkmark/public_html/mailer.php on line 4

Any ideas?

Most likely, the function is contained in an external file, and the include that points to that file is not working. There are two types of PHP includes, include() and require(), and if you use include(), the script will execute even if the inclusion fails. Try changing it to require(), which will break the script when it fails. That should at least narrow down the source of the problem, and possibly give you a meaningful error message to troubleshoot.
