$extraValues = array(

     'Shoe Polish' => 10, 
     'In-souls' => 15 
    ); 

    $trainerValues = array(

    if(isset($_POST['firstname'])){ 
     $firstname = $_POST['firstname']; 
     echo "Firstname $firstname <br />\n";

    $extraCost = 0;

    } // this brace was missing and causing your error 

    // if this is the name then use array_key_exists in the if statement below 
    $trainer = $_POST['trainers']; 

    if (array_key_exists($trainer, $trainerValues)) { 
     $trainerCost = (float) $trainerValues[$trainer];

    } 

    // add 20%, and round to 2 decimal places... 
    $totalCost = round(($extraCost+$trainerCost+$totalCost)*1.2, 2);
