Form is not sending email and not redirecting to thankyou page
I am sorry if this question appears somewhere else in the forums, I searched but could not find an answer.
I followed the instructions to set up my contact form: I started with the contactus file given by this site. I added checkboxes, a little css and deleted the captcha. I changed the email address in the WA_Globals.php and uploaded everything.
The validation works fine, but when submitted it does not redirect to the thankyou page. And I am not receiving the email.
you can view my page at: contactus.php
I appreciate the help!
