I've multiplied the $integerOne by $floatOne using echo ($integerOne * $floatOne); and receive an error

Challenge Tasks 1 + 2 have been completed correctly. In Challenge task 3 I've added the above line. When I check the results it shows "9" which would suggest the code does what is asked of it (multiply 6 by 1.5). The error however says I should use echo instead of var_dump but that is exactly what I'm doing

index.php 
<?php

//Place your code below this comment
$integerOne = 1;
$integerTwo = 2;
$floatOne = 1.5;

$integerOne = $integerOne +5;
var_dump ($integerOne);
$integerTwo = $integerTwo -1;
var_dump ($integerTwo);

echo ($integerOne * $floatOne);

?>

Try removing everything from your script that the tasks never asked for. The system can be picky

Let me know if this helps here

Thanks! I removed some lines and it worked out. I thought the idea was to keep the 1/3 and 2/3 code that was there :)

Ya, the tasks never explicitly asked for var_dumping and that ended up catching up with you in task 3.
