help on uploading code program into Arduino (LSM303DLH)

Using Arduino Project Guidance
#1

So I’m trying to upload this program into my arduino to LSM303DLH

and this is the kind of error that I"m getting.

I tried everything and it still gives me this error.

"avrdude: stk500_getsync(): not in sync: resp = 0x00
"avrdude: stk500_disable(): protocol error, expect = 0x14, resp = 0x51

here is my code below

#include <Wire.h>
#include <LSM303DLH.h>

LSM303DLH compass;

void setup() {
	Serial.begin(9600);
	Wire.begin();
	compass.enableDefault();

	//North_Heading is whatever heading the unit reports when you point it North 
	#define NORTH_HEADING 10 //originally offset by 10 degrees (adjusted the code below to obtain 0 degrees as north) 

	// Calibration values. Use the Calibrate example program to get the value for 
	// your compass. 
	compass.m_min.x = -90; compass.m_min.y = -90; compass.m_min.z = 0;
	compass.m_max.x = +90; compass.m_max.y = +90; compass.m_max = 359;
}

void loop() {
	// reads the heading value of 0 to 359 from compass 
	// Returns the number of degrees from -Y axis that it 
	// is pointing
	compass.read();
	int heading = compass.heading((LSM303DLH::vector)(0 -1 0));
	heading = ((heading - NORTH_HEADING) + 360) % 360;
	//heading is now a number between 0 - 360 with 0 corresponding to North 
	Serial.println(heading);
	delay(1000);
}
