RF 315 works but with NeoPixel in Pin 6 fails

Hi , I'm having problems in which I can't figure out what is happening.

I have:

When I get it all hooked up with the arduino on 5v and the neopixel on 5v I can only get a change in state when I get really close with the remote to the arduino unit. When I remove the Neopixels from Pin 6 on each unit and read out the serial. I get the proper inputs and can read them out.

I asked one fellow student who said it could be the interrupt that could conflict with the interrupt in the Neopixel library.

What should I do to go past the interrupt? And is it the interrupt? Below is my code:

//These are the libraries required.
//The adafruit Neopixel is for controlling the LED's.
//The HSBColor is for controlling the colors in Hue, Saturation and Brightness.
#include <Adafruit_NeoPixel.h>
#include <HSBColor.h>

//This is the PIN to
#define PIN 6

Adafruit_NeoPixel strip = Adafruit_NeoPixel(24, PIN, NEO_GRB + NEO_KHZ800);

#define DEFAULT_LED_SPEED 2800
#define MIN_LED_SPEED 5000

#define MAX_LED_SATURATION 99
const int saturationStep = 20;

long interval = 500; // interval at which to blink (milliseconds)
long intervalUp = 3000;
long intervalDown = 12000;
long previousMillis = 0; // will store last time LED was updated

int maxBrightness = 99;
int minBrightness = 0;

int stepDirection = 1;

// getRGB function stores RGB values in this array
// use these values for the red, blue, green led.

what's the output of the program?
