Hello everyone. I'll start by saying thank you for providing so much info on this forum. I am building a sim racing wheel and now that I am at the programming step I am stuck. I found a sketch on the web but I keep getting error expected unqualified-id before '.' token.  
I've tried couple of things to fix it but I am a newbie in this language so I am limited on ,what I can do about it.  
I have all the libraries downloaded. I am using Arduino 1.8.12 with Arduino Pro Micro

so this is the sketch that I ma trying to work with.

```cpp
//BUTTON BOX 
//USE w ProMicro

    };

      Joystick.setButton(rotaries[i].cwchar, 1); delay(50); Joystick.setButton(rotaries[i].cwchar, 0);
    };
  }
}

```

The other thing is that I can't find Arduino Pro Micro in the list.  
There is Micro and there is Pro & Pro mini.

Ho and when I copy the error message this is what I have.

Any help will be very appreciated.

The error line looks like you're trying to declare a joystick object. There are two issues: there's a period ('.') that shouldn't be there. Also, you're apparently declaring a variable Joystick of type Joystick. The two things can't have the same name - check your library examples to see how to do it - which one are you using?

Hello guys. Thanks for the quick answer. As I said I am a newbie in all of this so I am not sure of all the terms you are using. I've start reading on the "[w3shcools.com](http://w3shcools.com)" website so I can learn what I can but I don't understand much so far.  
Since my knowledge in C++ language is far from writing a sketch I looked and found this sketch from 2 different YouTube channel where it seems to work fine. I've contacted them both and I obviously haven' t received any answer.  
The Joystick library that I am using is "Joystick" from Giuseppe Martini V1.0.0  
When you said "the two things can't have the same name" I am not sure what things you are talking about.  
Sorry. Very noob...

The first Joystick on the line is defining the type of a variable. The second is the name of the variable. They cannot be the same. In the example that comes with the library the second one has a lower case 'j' i.e joystick.

Delete the dot, change the second Joystick to joystick and when you recompile you'll get some new errors to fix.

Hello WildBill. Thanks again for your help.  
I did changed the second Joystick for joystick and remove the dot.  
Now I have the error 'JOYSTICK\_REPORT\_ID' was not declared in this scope.
