Hi Reginald,

I'm assuming you are on task 2.

There are two simple problems with your subtraction statement: You have a capitalized integerTwo and you put two semi-colons at the end of that statement.

It doesn't hurt, but you don't need any echo statements at this point (task 2).

Hope this helps!

The extra semi-colon won't prevent the code from passing.
