Multiplying variables in PHP

Okay, I've formatted this a few different ways and it just tells me to make sure I'm using echo instead of var_dump. And to be fair, I was trying it with var_dump at first. But I can't figure out what could be wrong with this. It seems like it should work to me

index.php 
<?php
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;
$integerOne = $integerOne + 5;
var_dump($integerOne);
$integerTwo = $integerTwo - 1;
var_dump($integerTwo);


$total = $floatOne * $integerOne;
echo($Total);


?>

It appears the checker doesn't like the var_dumps so delete those. Then if you change the case of your total variable to match where it was assigned, echo($Total) to echo($total), you should pass.
