[Phpwm] Captcha Help

[Matt McConnochie]

Hi all - firstly thanks to those who pointed me in the correct direction for 
Captcha's. I think i am nearly there in incorporating this into our current 
form on our 'contact us' page.

The email addy on the form is a required field . I want the captcha to be 
required also but i seem to have a problem that the captcha can be bypassed. 
I have included most of the code below  so any thoughts / ammendements would 
be useful.

To summarize - i need a single click on the 'submit' to check the captcha 
and user entered email and if all is well with the form to post this so us. 
I think it could be something like the input types for the form.

Any help would be greatly appreciated

Mr Noob :)
