Forms and IE

Please forgive me if this has been covered before. I have searched the list and could not find reference to a similar problem. I am completetly new to PHP and I am stuck. I am creating a very simple form. Essentially the user agrees or disagrees to a message. If the user agrees, they are sent to another form. It they disagree they are sent home. My script works with Netscape and Opera but not Internet Explorer (ver 6.0.2) and I cannot figure out why. As I said it is very simple and the relevant parts are displayed as follows: <form method="post" action="agree.php> ...... I have read the terms and Agree <input type="checkbox" name="agree[]" value="agree"> I Do Not Agree <input type="checkbox" name="disagree" value="disagree"> <input type="submit" name="submit" value="Submit"> ....... "agree.php" <? if ($agree) /* (I have tried this also with ($isset = $agree)) */ { header ("location: ?link=form"); } else { header ("location: /LETS"); } ?> As I said, this works fine with Netscape and Opera but not IE. Any suggestions and/or advice is appreciated. Thanks. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
