That's not terribly helpful, can you post the exact error output and perhaps post the code on and around line 32?

It looks to me like you're closing PHP scope early (?>), and some of your PHP code is being sent to the browser as plain HTML.


Take care,

Nik

Sorry about that.
Depending on when I view the page with IE or within Allaire Homesight, I get different errors:

IE
Notice: Undefined variable: line 138

Allaire Homesight, :
Error has occured in the script on this page
Line 32
character 7
Invalid Character
code 0


here is the entire page:
I think the error comes somewhere in the function error_message() and user_message() ?...

<?php
//simple_mailer.php

function mailer_header()

   mailer_footer();

Most likely, you have register_globals set to "off" in php.ini. The actual error message that PHP issues (what's shown in IE) should tell you the name of the undefined variable.

Look in php.ini (or run a <?php phpinfo(); ?> script) and verify your register globals setting.

For more info on register globals, start here:
  http://p2p.wrox.com/archive/beginnin...2002-11/17.asp

There are hundreds (if not thousands) of posts on P2P about this issue:

If that's not your problem, let us know.


Take care,

Nik
