I have a Captcha installed on my "Subcribe to Mailing List" form that runs well. The only thing is that I also have a "Unsubscribe" button on the same form and it also calls the same Captcha. How can I have the Captcha to run only on the "Subscribe" button and not the "Unsubscribe"?
The CAPTCHA comes from a Dreamweaver Plug-in
Your form have two buttons, and I supose that both execute different actions. You must isolate the point where you call the captcha and make that it doesn't execute when action from unsubscribe button is called.
If the captcha is launched on the form onsubmit event you should detect on client code wich button has been clicked before submitting and cancel the captcha execution.
