PHP form isn't working - php

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" >

The server is set up for PHP.
If it would be of any help, you can check the form out here:http://student.mtstudent.se/~sh14hf2407/pages/formular.html

Answer 1

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.

Answer 2

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