Thank you for trying to help but this is getting frustrating...its 8 days later and the form is still not working as we'd like. There are 2 issues still to resolve.
First, by changing the form action to <form action="" method="post" name="ContactUs" id="ContactUs" >, the captcha is executed but the form results are no longer posted.
How can we have it that the form is validated with spry elements, captcha image is verified and the form is posted and results recieved by email ?
Second, no when an erroneous value for the captcha is entered, the form automatically re-loads, clears all fields and gives the (desired) "Your security code entry did not match the image" error message. How can it be set that only the error message appears and the form fields are not cleared?
