chronoform not working

I have two chronoforms on my site. One works just fine, the contact form.

The other, a registration form isn't working. I'm not getting an email after someone registers on the form, with their registration information. Nothing comes. And I'd love the page to stay at the bottom of the page after someone registers and clicks 'submit', where the registration form is, and show something like, "Thank you for registering. You will be receiving an information email very shortly."

You can see the form at the bottom of this page:
REMOVED

Can anyone help?

Thanks.

Hi,

If you have the cache enabled then please try to disable the "Relative url" setting under the "HTML" action.

I set the "Relative url" to "No" and when I tested the form, the message showed however on top of the message was this error message: Mailer Error: Could not instantiate mail function.

BTW I gave you the incorrect page to look at. The correct page is:
http://www.processcoaching.com/teleconference-class.html

Could you please edit my first post and remove the incorrect url. Thank you.

The "Could not instantiate mail function" is a mail function issue, what's the mailing method in your Joomla global config ? and do you receive email from your website ?

Well interesting. I have a contact us form that was working yesterday. Now I'm getting this error message for that form also:
Mailer Error: Could not instantiate mail function.
Mail setting in global config is set to PHP mail.
The contact page is: http://www.processcoaching.com/contact

Plus this shows up on the contact us page after trying to submit: I've removed some of the personal information, such as email, and name.

You are receiving a "not" sent message, which means that your email config is wrong, you don't have some or any of the following:

To, subject, from name and from email

Those 4 items are mandatory!

Max

As I said in my post: I've removed some of the personal information, such as email, and name.
These 4 items (to, subject, from name and from email) are there, I just removed them in my post to protect my privacy.
Is there some support so I can get these forms working? Maybe by private email?

Please send a message using the "contact us" page

I sent a message early this morning, and look forward to hearing back from you. Thanks.
