title: Call to undefined function session_set()
body: <p>My page returns this error:</p>
  
  <blockquote>
    <p>Fatal error: Call to undefined function session_set()>in /home/a7714221/public_html/index.php on line 5</p>
  </blockquote>
  
  <p>My code is long on the page that returns the error but the only thing that could cause it of course is the session_set()</p>
  
  <p>Anybody know the fatal error that I've inadvertently made? :) </p>
  
  <p>EDIt: I'm trying to pass variables across several pages. Specifically, take $_POST data, subtract it from another variable then ask the user to enter another value and subtract it from (previous post data - afore mentioned variable) and so on until it reaches 0.</p>
