PHP form isn't working

Question

Can anyone see what's wrong with these two files? When I click submit, it just redirects me to a blank page and I get no feedback from the form what so ever let alone an email.

HTML code

    <form action="../script/form14.php" method="POST" >

    <h1>KittyBoo</h1>
        <p>Beställ kattmat online - alltid laktos- och glutenfri</p><fieldset class="formular">

      // message lines should not exceed 70 characters (PHP rule), so wrap it

The server is set up for PHP.

Answer 1

change

<input type="submit" value="skicka"> 

into

<input type="submit" name="submit" value="skicka">

Answer 2

Your PHP condition if (!isset($_POST["submit"])) { ... } is always FALSE because $_POST['submit'] doesn't exist in your html form. You have created an element <input type="submit" value="skicka"> but $_POST['submit'] means "an element which name attribute is submit". So replace :

<input type="submit" value="skicka">

by

<input type="submit" name="submit" value="skicka">

and this issue will be fixed.
