You need to read up on variables, functions, and argument passing. It appears that your info() method wants to use arguments passed by reference.

Good luck! |

| The errors in this are not that hard to fix, but there are a number of them! As Duoas said, read up some more then try again! |

| Ah,seems that you still don't know how to call a function...Read more about the rules and you can find the problem easily. |
