1,534 PointsHow do I reference the variables in the echo'd message for this exercise properly?
I receive a "Use the variables to display the student name" error when running the below code:
<?php $studentOneName = 'Dave'; $studentOneGPA = 3.8;
$studentTwoName = 'Treasure'; $studentTwoGPA = 4.0;
if ($studentOneGPA == 4.0) { echo "$studentOneName made the Honor Roll"; } else { echo "$studentOneName has a GPA of $studentOneGPA"; }
if ($studentTwoGPA == 4.0) { echo "$studentTwoName made the Honor Roll"; } else { echo "$studentTwoGPA has a GPA of $studentTwoGPA"; }
?>
I would appreciate some advice regarding how to fix the above so that the variables are correctly referenced within each echo'd string.
<?php
$studentOneName = 'Dave';
$studentOneGPA = 3.8;
$studentTwoName = 'Treasure';
$studentTwoGPA = 4.0;
if ($studentOneGPA == 4.0) {
echo "$studentOneName made the Honor Roll";
}
else {
echo "$studentOneName has a GPA of $studentOneGPA";
}
if ($studentTwoGPA == 4.0) {
echo "$studentTwoName made the Honor Roll";
}
else {
echo "$studentTwoGPA has a GPA of $studentTwoGPA";
}
?>

9,244 PointsYou used $studentTwoGPA instead of $studentTwoName, so the system thought you manually entered student #2 name.
<?php
if($studentTwoGPA == 4.0) {
echo "$studentTwoName made the Honor Roll";
} else {
echo "$studentTwoName has a GPA of $studentTwoGPA";
}
?>
