I am trying to use the Arduino analog pins as digital inputs with the joystick sketch

General information for the business: Personal Project.
Kind of development: Customization of existing program
Description of requirements/functionality: I literally want to use the analog pins on the Arduino Leonardo as digital pins to increase the number of inputs so I can use more than 12 buttons with the joystick sketch. It looks like it should be simple to do so I am sure I am making some dumb mistake. Here is what I have, it is basically one of the example sketches with extra digital pins added.

#include

void setup() {
// Initialize Button Pins
pinMode(1, INPUT_PULLUP);
pinMode(2, INPUT_PULLUP);
pinMode(3, INPUT_PULLUP);
pinMode(4, INPUT_PULLUP);
pinMode(5, INPUT_PULLUP);
pinMode(6, INPUT_PULLUP);
pinMode(7, INPUT_PULLUP);
pinMode(8, INPUT_PULLUP);
pinMode(9, INPUT_PULLUP);
pinMode(10, INPUT_PULLUP);
pinMode(11, INPUT_PULLUP);
pinMode(12, INPUT_PULLUP);
pinMode(13, INPUT_PULLUP);

// Initialize Joystick Library
Joystick.begin();
}

// Constant that maps the phyical pin to the joystick button.
const int pinToButtonMap = 1;

// Last state of the button
int lastButtonState[13] = {0,0,0,0,0,0,0,0,0,0,0,0,0};

void loop()


And that is it, I am sure this is going to be easy for anyone familiar with this system to sort out. Thanking you in advance for your help. John Hyde.
