Help with If Statement

What I am trying to do is to get a stepper motor to read an input from an IR sensor and turn either left or right. I got the code to wrok using a switch statement from earlier, but the problem was this:

When a button was pressed, it ran the code all the way through. What I need is a way to break the loop if a new button is pressed. We have three buttons, one to turn the motor to the left, one to turn the motor to the right and one to stop the motor. We managed to get the hex and decimal versions of the buttons. The error I get is this:

StepperPractice.cpp:34:9: error: invalid suffix "Received" on integer constant

I get it for all three If statements even though I commented out some of it. Any idea why it is wrong?

#include <IRremote.h>

#define button1 16582903
#define button2 16615543
#define button3 16599223
#define RECV_PIN  10

IRrecv irrecv(RECV_PIN);
decode_results results;
long lReceived = 0 ;

#define DIR_PIN 2
#define STEP_PIN 3

void setup() {
  pinMode(DIR_PIN, OUTPUT);
  pinMode(STEP_PIN, OUTPUT);
  pinMode(RECV_PIN , INPUT);
  
  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
} 

void loop(){ 
 if (irrecv.decode(&results)) {
    lReceived = results.value ;

    if (1Received == button1){
      digitalWrite (STEP_PIN, HIGH);
      digitalWrite (DIR_PIN, HIGH);
      //rotate a specific number of degrees 
      rotateDeg(3600, .5);
      delay(1000);
    }
//    if (1Received == button2){
//       digitalWrite(STEP_PIN, LOW);
//       digitalWrite( DIR_PIN, HIGH);
//    }
//    if (1Received == button3){
//      digitalWrite( STEP_PIN, HIGH);
//      digitalWrite( DIR_PIN, LOW);
//      rotateDeg(-3600, .5);  //reverse
//      delay(1000);
//    }
    
    irrecv.resume(); // Receive the next value
  }
}

void rotateDeg(float deg, float speed){
  //rotate a specific number of degrees (negitive for reverse movement)
  //speed is any number from .01 -> 1 with 1 being fastest - Slower is stronger
  int dir = (deg > 0)? HIGH:LOW;
  digitalWrite(DIR_PIN,dir); 

  int steps = abs(deg)*(1/0.225);
  float usDelay = (1/speed) * 70;

  for(int i=0; i < steps; i++){
    digitalWrite(STEP_PIN, HIGH);
    delayMicroseconds(usDelay); 

    digitalWrite(STEP_PIN, LOW);
    delayMicroseconds(usDelay);

  }
}

How is the IR sensor connected to the stepper motor? What programming do you have on the stepper motor?

    if (1Received == button1){

Variable names can't start with a number.

I have the IR sensor connected to Pin 10 on the Arduino which is an input. It is also connected to the ground and power from the Arduino. For the motor, the programming I used is the BigEasyDriver along with a seperate driver. The driver has two outputs Dir and Step. Step turns the motor on/off whereas Dir turns the motor CW or CCW. Pin 2 and 3 is used to read the output from the arduino telling the motor what to do via the driver.

And thanks. That did the trick.
