I have a webform that uses Javascript to validate the fields. Once the required fields are filled in then the form is submitted to sendmail.asp to send the email.

I'm trying to incorporate the Web Wiz Captcha within the form page rather than redirect to the process page but cannot get Javascript to validate the Captcha value.

I have pasted the code from your process_form.asp file to my contact form page but cannot get it to work.

My form tag is <form action="sendmail.asp" method="POST" onsubmit="return Form1_Validator(this)" name="Form1">

The CAPTCHA value cannot be validated using JavaScript as the response needs to be sent to the server where the value is compared to the CAPTCHA value held in the web servers memory.

If it was processed client side in JavaScript then it would be easy for a bot to get around the CAPTCHA.

I dont want to incorporate the validation in to Javascript but rather have the validation on the same page after the Submit rather than take the user to a new page showing the Captcha failure it would be better to display a message that the Captcha was wrong.

You would need to submit the form back to the same page.

See the Advanced install documentation at the link below;
