$integerOne = 1; $floatOne = 1.5; var_dump($integerOne * $floatOne); why doesn't this work in the Tasks quiz?

When I write this in Workspaces, I get the correct answer of float(1.5). When I try to enter this answer into the Tasks Quiz I receive the response "Bummer, integerOne is unchanged." Does anyone know why this isn't working? Thanks for your help!

index.php 
<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
var_dump($integerOne);
$integerOne = $integerOne + 5;
var_dump($integerTwo);
var_dump($integerTwo--);

$integerOne = 1;
$floatOne = 1.5;
var_dump($integerOne * $floatOne);


?>

Don't re-assign the variables back to their initial values. Task 3 is expecting to see the results based on the values they have after task 2.

Also, for the purpose of the challenge, you won't need to use any "var_dump"s. When it asks you to display the final result, use "echo".

Thank you, Steven. I'll give this a try.
