Arduino pin descriptions
Where the sketch initialises the LiquidCrystal library, substitute the pin numbers you are actually using

LiquidCrystal lcd(13,12,11,10,9,8); // RS, Enable, D4,D5,D6,D7


The Arduino Uno in your Fritzing diagram has the following pinout



You GizDuino+ has



The usual LCD pinout is



So you are possibly using pins 8-13 instead of 0-5 (4 x data, enable, rs)

If you installed the gizDuino cores in the Arduino IDE, you should be using 8-13, the compiler will produce the correct code
