Hi there!
Firstly I’d just like to thank you for all your help towards us fellow makers/tinkerers!
so, I have followed this tutorial: Overview | Wireless NeoPixel Controller | Adafruit Learning System to create a remote controller for neopixels,
My aim is to apply this controller to trigger various fire effects replacing some of the pre-set effects already in the reciever code such as rainbow fade ( which I am currently trying to replace with fire2012 FastLED/Fire2012.ino at master · FastLED/FastLED · GitHub)
I have managed ( with some help) to achieve this, however it only works on the first LED on a strip of 60, if any one can please help me with some advice as to overcome this problem it would be hugely appreciated 
my code is as follows :
#include <FastLED.h>
#define FRAMES_PER_SECOND 30 // %%%%%%%%%%%%%%%%%% best guess for this
#define LED_PIN 12
#define NUM_LEDS 144
#define LED_TYPE WS2812B
#define COLOR_ORDER GRB
#define COOLING 55
#define SPARKING 120
CRGBArray<NUM_LEDS> leds;
#include <SPI.h>
#include <RH_RF69.h>
#include <Wire.h>
#define LED 13
