'PORTH' was not declared in this scope -ERROR

hello, I'm really new in this arduino world.

Currently I'm doing the programming coding example given by Adafruit to test my 3.5" TFT LCD Shield for Arduino (ILI9481) with my Arduino Mega.

But the ('PORTH' was not declared in this scope) error is popping up when I verify the programming.Can somebody help me to get better understanding. Btw, I'm really new like the first day new =__=
