2,510 PointsAttempting to complete Step 3 of the challenge after the unit converter.
Step 2 validates, but step 3 throws an error, "Oops! It looks like Task 2 is no longer passing." And the output looks correct to me. My code follows:
<?php
//Place your code below this comment $integerOne = 1; $integerTwo = 2;
$integerOne += 5; $integerTwo -= 1;
$floatOne = 1.5; $integerOne *= $floatOne; echo $integerOne; ?>
What am I not seeing?

Treehouse TeacherHi there! Your code is functional and it does produce the output you would expect. However, the challenge wants you to do this without overwriting the value of $integerOne. Currently, the end value of $integerOne is 9 because you have this line:
$integerOne *= $floatOne;
Try again by echoing directly $integerOne times $floatOne. If these hints weren't enough, please let me know. Good luck!

2,510 PointsAlso interesting, in the third step I tried:
''' $result = $integerOne * $floatOne; echo 9; '''
And it passed the end of the challenge. Heh.

2,510 PointsThank you. Interestingly, I got around it by creating a new variable $result to hold the result of the multiplication and echoing that instead. Which I thought was odd because the parser can't possibly be looking for that variable. How do they know that my final result was correct without validating that?
