Treehouse TeacherHi there! The most common reason this will happen is because of a syntax error. However, you've run into one of those rather rare scenarios in which you've changed the value of a variable which you weren't supposed to change. In the third step, you are supposed to echo out directly the result of multiplying $integerOne with $integerTwo. But you've replaced the value of $integerOne with that result and then echoed it out.
Imagine that I add this line to the instructions: Do this without changing the values of any of the variables from the previous steps.
I think you can get it with these hints, but let me know if you're still stuck!

487 PointsDear I changed the code as follow and now its working .But I really dont have a clear image about this process.
$multiply = $integerOne * $floatOne;
echo $multiply ;

Treehouse TeacherHi there! The challenge also doesn't ask you to use a new variable. It wants you to echo out the value directly like this:
echo $integerOne * $floatOne;The reason you got the error to begin with was because you had this line:
$integerOne *= $floatOne ;This line takes integerOne and multiplies it by floatOne, then assigns the result back into integerOne. This means that although the value of integerOne should be 6, it is now 9.
