Arduino UNO - Controling LED strip with presure sensor & pulse sensor

Hi all, I am new to forums and hope someone can help me.
I have two separate sketches both working fine, the pressure sensor and the pulse sensor; alone these are fine but when I try to combine both they stop working on me can anyone please help ? =(

//Code for pressure sensor
int fsrAnalogPin = 0; // FSR is connected to analog 0
int LEDpin0 = 11; // connect Red LED to pin 11 (PWM pin)
int LEDpin1 = 10;
int LEDpin2 = 9;
int fsrReading; // the analog reading from the FSR resistor divider
int LEDbrightness;

void setup(void) {
Serial.begin(9600); // We’ll send debugging information via the Serial monitor
pinMode(LEDpin0, OUTPUT);
pinMode(LEDpin1, OUTPUT);
pinMode(LEDpin2, OUTPUT);
}

void loop(void) {
fsrReading = analogRead(fsrAnalogPin);
Serial.print("Analog reading = ");
Serial.println(fsrReading);

// we’ll need to change the range from the analog reading (0-1023) down to the range
// used by analogWrite (0-255) with map!
LEDbrightness = map(fsrReading, 0, 1023, 1, 255);
// LED gets brighter the harder you press
analogWrite(LEDpin0, LEDbrightness);
analogWrite(LEDpin1, LEDbrightness);
analogWrite(LEDpin2, LEDbrightness);

delay(100);
}

//Code for pulse sensor comes in two tabs this is the first tab
int analogPinR = 11;
int analogPinG = 10;
int analogPinB = 9;
//the buffer
int RGB[9];
//VALUES OF Red green and blue

int R=0;
int G=0;
int B=0;
int pulsePin = 1; // Pulse Sensor purple wire connected to analog pin 0
int fadeRate = 0; // used to fade LED on with PWM on fadePin
//int fadePin = 9; // pin to do fancy classy fading blink at each beat
//int fadePin1 = 10; // pin to do fancy classy fading blink at each beat
//int fadePin2 = 11; // pin to do fancy classy fading blink at each beat
// these variables are volatile because they are used during the interrupt service routine!
