What am I doing wrong?

I am trying to figure out what is wrong with my code.

<?php $studentOneName = 'Dave'; $studentOneGPA = 3.8;

$studentTwoName = 'Treasure'; $studentTwoGPA = 4.0;

//Place your code below this comment if ($studentOneGPA == '4.0') { echo '$studentOneName made the Honor Roll.'; } else { echo '$studentOneName has a GPA of GPA';

} ?>

index.php 
<?php
$studentOneName = 'Dave';
$studentOneGPA = 3.8;

$studentTwoName = 'Treasure';
$studentTwoGPA = 4.0;

//Place your code below this comment
if ($studentOneGPA == '4.0')
{
  echo '$studentOneName made the Honor Roll.';
} else {
  echo '$studentOneName has a GPA of GPA';


}
?>

Can you make your comment into an answer so people can give you upvotes and best answers? It actually gives you bonus points (if you get upvotes/best answers).

Yep, Phil's answer is right! And ditto what Alexander said.

Thank you for helping me. I don't understand why I am still getting an error though. It says "Bummer! You need to check that $studentOneGPA is equal to 4.0"

It's the single quotes on lines 11 and 13 preventing the variable values from being printed to screen. In order to fix it you can either use double quotes or single quotes with string concatenation. e.g.

Single quotes with string concatenation

<?php
    $studentOneName = 'Dave';
    $studentOneGPA = 3.8;

    $studentTwoName = 'Treasure';
    $studentTwoGPA = 4.0;

    //Place your code below this comment
    if ($studentOneGPA == '4.0')
    {
        echo $studentOneName . ' made the Honor Roll.';
    } else {
        echo $studentOneName . ' has a GPA of ' . $studentOneGPA;
    }
?>

Double quotes

<?php
    $studentOneName = 'Dave';
    $studentOneGPA = 3.8;

    $studentTwoName = 'Treasure';
    $studentTwoGPA = 4.0;

    //Place your code below this comment
    if ($studentOneGPA == '4.0')
    {
        echo "$studentOneName made the Honor Roll.";
    } else {
        echo "$studentOneName has a GPA of $studentOneGPA";
    }
?>
