Thats because you are including 2 other files too in your php code so the resulting line would be different:

include( "../config.php" );
    include( "product.php" ); 

Edit:
Ok ,just had a look at your code, The error is in line number 102

        ( "../upgrade/", $nextButton );
        $upgrade = new Upgrade( ); 

Remove that line 101 or fix it, thats incorrect
