Close. You need to concatenate an actual string literal to the firstName variable. You can do this by:

firstName + " rocks!"

When you just add the + rocks! without the use of quotations, the compiler begins to looks for a variable named rocks!, which doesn't exist. Resulting in a compile error. So try adding the quotation marks :]
