PHP is case sensitive. Additionally, quotes, or the absense of quotes, can change the context. I bring this up because the example you have above, $_post[sender_email] contains two errors: * $_post will likely be empty, whereas the PHP superglobal $_POST will likely contain the data you're looking for ;-) * $_post[sender_email] refers to the value in the $_post array returned by an array key that is the same name as the value of the constant sender_email. You almost certainly were actually meant $_POST['sender_email'] (note the quotes), which would refer to the value associated with the array key 'sender_emaail' in the $_POST array. You should probably do some reading in the introductory chapters of the PHP manual, specifically the variables section: http://php.net/variables Cheers! -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/
