How to check whether GPA is equal to 4.0? I used this logic: If ($studentOneGPA==4.0)

The system said I need to check if GPA equal to 4.0 but I have done that already with my code. Haven't I?

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

PHP is case-sensitive, which means that you have to type its keywords exactly, and it matters if its letters are capital or lowercase. In both places it's written, the "I" in if is capitalized in your code, but the proper keyword is all lowercase. Furthermore, I believe that you'll also have to use string concatenation if you want the value of the variable pasted into your string instead of the variable name. For example:

<?php
$studentName = "Michael"
echo "My name is $studentName"; // echos "My name is $studentName"
echo "My name is " . $studentName; // echos "My name is Michael"
?>
