Hi there! You're doing really well here. They do say to display the results of integerOne multiplied by floatOne. What they are expecting here is for you to display the result without displaying the entire information contained in a var_dump. It's expecting an echo statement to be used here.

Challenges can be very strict and if you do something it's not expecting, it can cause the challenge to fail even if it's functional. To get this to pass, I removed all your var_dump lines as they are not required by the challenge. And the line you're missing is an echo statement that looks very much like the code you've already written. :thumbsup:

Take a look:

echo $floatOne * $integerOne;

Hope this helps! :sparkles:

Other than removing the var_dump and adding that echo, I'm not sure what to tell you. This code passes all three steps for me.

<?php

//Place your code below this comment

$integerOne = 1;
$integerTwo = 2;
$integerOne = $integerOne + 5;
$integerTwo = $integerTwo - 1;
$floatOne = 1.5;

echo $floatOne * $integerOne;

?>

You might consider restarting the challenge if you're still experiencing problems.
