Can you help me to get the Contact Page to work?

I have followed the instructions with no success. I am in the set mode. I want the wemail to be sent to the hidden field "webmaster" which is my address the return to the home page caps_home.php. I never get an email nore does the page return to the caps_home after submit. You can find the page on https://caccaphoto.org/caps/contact_us.php

Your form action is set to: action="caps_contact_us.php"

It has to be set to the current page name or the code on the page won't have a chance to run. That appears to be your issue.

I made the form change to contact_us,php

Please attach the current page you are working on so I can verify the change was made properly. Does it redirect to the success page? Please include any details that might help me identify the issue.

I changed line 109 by changing the action to contact_us.php

That looks correct now... After you submit the form does it go to the caps_home.php page? Are there any errors on the page?

No it doesn't go to the caps_home page and there are no errors. After the processing display clears the form Contact Us page is refreshed and this appears above the security code. It is like the CAPTCHA validation isn't working. Another question. When the question is "Which day comes before tuesday?" is te Answer * case sensitive? monday or Monday

Neither are case sensitive. If it doesn't get passed this, then it might be that your server isn't saving session variables properly. To test this, create two pages.

setSession.php with code:
<?php
@session_start();
$_SESSION['test'] = "works";
?>

and viewSession with code:
<?php
@session_start();
echo(isset($_SESSION['test'])?$_SESSION['test']:"does not work");
?>

Then browse the setSession.php page with your browser and then go to the viewSession.php page after to see if it works.

Can you put your contact page on a live site and give me FTP access? That would allow me to do some testing and figure out what is wrong on my own.

Thanks for your help. I scrap the page and started from scratch and it work fine.
