Why doesn't quiz accept my output?

This challenge is a little confusing to me. My two if statements compute but the quiz doesn't like the output. Do I need to create two new variables (NAME and STUDENTGPA)?

Here is the text from the quiz "

Check if each student has a GPA of 4.0.

If the student has a GPA of 4.0, use the student name variable to replace NAME when displaying the following line:

NAME made the Honor Roll

ELSE If the students GPA is not equal to 4.0, within an else block, use the student name variable to replace NAME AND the student GPA variable to replace STUDENT GPA when displaying the following line:

NAME has a GPA of STUDENT GPA "

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

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

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

if ($studentTwoGPA === 4.0){
  echo "$studentTwoName has made the Honor Roll";
} else {
  echo "$studentTwoName has a GPA of $studentTwoGPA";
}

?>
