Error compiling for board Arduino Mega or Mega 2560.

Development Tools IDE 1.x

I'm working on learning how to use a LCD Touch Screen and I can't get my code to compile. Sorry if this is a common error, I did do my best to search around and find a solution on my own but I didn't have much luck.

Here is my error

Code
#include <UTFT.h>
#include <URTouch.h>

UTFT myGLCD (SSD1963_800ALT,38,39,40,41);
URTouch myTouch (6,5,4,3,2);

extern uint8_t SmallFont [];
extern uint8_t BigFont [];
extern uint8_t SevenSegNumFont [];

void setup() {
myGLCD.InitLCD();
myGLCD.clrScr();
myTouch.InitTouch();
myTouch.setPrecision(PREC_MEDIUM);
myGLCD.setBackColor(0,0,0);
myGLCD.setColor(255,255,255);
myGLCD.setFont(BigFont);
myGLCD.print("Hello World!", CENTER, 10);
}

Thank you for any and all help

Every Arduino sketch must have a setup() and a loop() function. Your sketch is missing the loop() function, which is the cause of the error.

You can learn more about loop() here:

That fixed the issue! Not new to Arduino's just haven't messed with them in a couple years!

Thank you very much!!
