Hi raghdahesham2,

After your first if/else you repeated the variables for student two and this seems to be throwing off the tester. Take those out because all the variables are already defined at the top of the starter code.

The other thing is that this challenge requires a stricter formatting of the code.

Try it like this: (It's still your same code but the curly braces are formatted differently)

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

Do that for both of them and you should pass.

All of your logic was correct.

You need to concatenate the strings with the variable. In your code, you are including the variable inside quotes, which then treats it as a string literal. Instead, your echo statements should look something like this:

echo $variableName1 . ' has a GPA of ' . $variableName2;

Hope this helps.

Variables are evaluated within double quotes in PHP. Within single quotes they are not and would be treated literally.
