The board uses different pins to the Arduino example sketches, so to make the display work, use the following sequence of pins when starting the library:

LiquidCrystal lcd(8,9,4,5,6,7);

The buttons are connected to only one analog input pin through resistors to give a different voltage for each button, thus saving on input/output pins
