Adding extra field control ( like CAPTCHA ) is not validated.

Hi all,

i installed CAPTCHA (http://www.zen-cart.com/index.php?main_page=product_contrib_info&cPath=40_47&products_id=325)

but the check is not performed at all.
When i leave it empty or typed in an incorrect code... it excepts the wrong code and the ContactUs mail has been send.

I followed the instructions, and got no error at all.
The code is INSERTED into the database correctly.
The options are shown in the AdminConsole and set to TRUE.

I have added a custom fieldcheck into the Contact Us page, and even that one is not checked at all.

Only the normal fields are check correctly ( email, name, etc. )

Whats wrong in the code?

Update:
The CAPTCHA code check in the registration page is wokring correctly. The Contact Us page is not working at all regarding the CAPTCHA check
