Andymark LED strip Programming Issues

So, I'm moderatly new to programming with Arduinos. I'm trying to set up this LED strip, and I'm trying to run the light chaser example. I included all of the relevant libraries (I get the feeling that I didn't do it correctly, even though It seems to be), but I'm getting a few errors whenever I verify the code.

The Error(s):

LEDchaser.cpp.o: In function `missing_dot_chase(unsigned long, unsigned char)':
C:\Program Files (x86)\Arduino/LEDchaser.ino:97: undefined reference to `FastLED'

The Code:
//This is a mashup of FastSPI_LED2 firstlight example and some other light chase hacks
//AndyMark, LLC
//Craig Kessler 12/3/2013
//Works with the AndyMark AM-2640 LED Strip based on the WS2801 chipset
//This code requires that the fastspi library be put in your arduino\libraries folder

//https://code.google.com/p/fastspi/
//https://code.google.com/p/fastspi/wiki/CRGBreference
#include "C:\Users\Maxwell\Google Drive\FRC_Programs\LED Strip\LEDchaser\FastLED.h"

// How many leds are in the strip? AndyMark's 2.5 meter strip has 80 leds
#define NUM_LEDS 80

//Remember on the AM-2640 LED strips yellow is ground! (don't blame us they come that way)

// Data pin that led data will be written out over
#define DATA_PIN 11 //Green Wire

// Clock pin only needed for SPI based chipsets
#define CLOCK_PIN 13 //Blue Wire

// This is an array of leds. One item for each led in your strip.
CRGB leds[NUM_LEDS];



// This function sets up the leds and tells the controller about them
void setup() {
// sanity check delay - allows reprogramming if accidentally blowing power w/leds
delay(2000);

// Uncomment one of the following lines for your leds arrangement.
FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);

// FastLED.addLeds<SM16716, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<LPD8806, RGB>(leds, NUM_LEDS);

// FastLED.addLeds<LPD8806, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
}

// This function runs over and over, and is where you do the magic to light
// your leds.

}

void color_chase(uint32_t color, uint8_t wait)
{
FastLED.clear();
FastLED.setBrightness(100);
// Move a single led
for(int led_number = 0; led_number < NUM_LEDS; led_number++)
{
// Turn our current led ON, then show the leds
leds[led_number] = color;

// Show the leds (only one of which is set to white, from above)
FastLED.show();

// Wait a little bit
delay(50);

// Turn our current led back to black for the next loop around
leds[led_number] = CRGB::Black;
}
}

//Move an "empty" dot down the strip
void missing_dot_chase(uint32_t color, uint8_t wait)
{
int led_number;

for (int led_brightness = 100; led_brightness > 10; led_brightness/=2)
{
FastLED.setBrightness(led_brightness);
// Start by turning all pixels on:
for(led_number = 0; led_number < NUM_LEDS; led_number++) leds[led_number] = color;

// Then display one pixel at a time:
for(led_number = 0; led_number < NUM_LEDS; led_number++)
{
leds[led_number] = CRGB::Black; // Set new pixel 'off'
if( led_number > 0 && led_number < NUM_LEDS)
{
leds[led_number-1] = color; // Set previous pixel 'on'
}
FastLED.show();
delay(wait);
}
}
}


I've been looking around, and I can't seem to much material on setting up this LED string, and coding for it.

If you need any more information, just say it

Help is always appreciated, whether it's for the error or general help programming the LEDs.
