The challenge is asking you to check if each student has a GPA of 4.0, there is no need to have any var_dumps, so you will need exactly 2 if statements and 2 else statements to see if studentOneGPA is 4.0 and if studentTwoGPA is 4.0.

If either of these conditions is true it asks you to echo "NAME made the Honor Roll" - remember we can use double quotes and the variable name to expand the variable into the value it has been assigned. For example if $name = "Chiratidzo", then we can use:

echo "Hello, $name"

The above code will replace $name with the value of Chiratidzo. Giving us "Hello, Chiratidzo".

It is also asking that when those statements are NOT true (i.e. using else statements after each if statement), then we must echo "NAME has a GPA of STUDENT GPA" - just as before we can use double quotes to expand the NAME and the STUDENT GPA variables.

What am I doing wrong here? 

<?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 $studentOneGPA GPA";
}

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

?>

I have also tried using the == comparison operator and it isn't working :/

Good job on the logic - it's all correct. The problem is that the challenge asks you to echo "NAME has a GPA of STUDENT GPA", whereas yours says "NAME has a STUDENT GPA".

You need to change your echo statements to match exactly what the challenge expects it to say.

It should be similar to this (not exactly):

echo "$studentName has a GPA of $studentGPA";
