My code is giving errors.
I'm new to Arduino, pls help me

#include <IRremote.h>
const int RED = 7;
const int GREEN = 6;
const int BLUE = 5;
int RECV_PIN = 11;

IRrecv irrecv(RECV_PIN);

decode_results  results;

void setup()
{
  pinMode (RED, OUTPUT); // Включить выходы
  pinMode (GREEN, OUTPUT);
  pinMode  (BLUE, OUTPUT);
  Serial.begin(9600);
  irrecv.enableIRIn();  // Start the receiver
}

void loop() {
  if (irrecv.decode(&results))  {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive  the next value
    if (results.value, HEX == FF30CF); {
      analogWrite(RED, 255);
      analogWrite(BLUE, 0);
      analogWrite(GREEN, 0);
    }
    else {
      if (results.value, HEX == FF18E7);{
        analogWrite(RED,0);
        analogWrite(GREEN, 255);
        analogWrite(BLUE, 0);
      }
      else {
        analogWrite(RED, 0);
        analogWrite(GREEN, 0);
        analogWrite(BLUE,255);
      }
    }
  }

Welcome to the forum

Please post the full error message, using code tags when you do

Where did you get this idea from? results.value, HEX

Further FF30CF is a variable because it starts with a letter. That should be 0xFF30CF.

Lastly that semi-colon does not belong there.

So that part of your code becomes

if (results.value == 0xFF30CF) {
      analogWrite(RED, 255);
      analogWrite(BLUE, 0);
      analogWrite(GREEN, 0);
    }

Repeat for the other ones.

4 
 if (results.value, HEX == FF18E7);

Whatever else might be wrong, the semicolon at the end of this line will mean that the code intended to be executed if the values match will be executed unconditionally

As to other problems, where is FF18E7 declared ?
What value are you actually trying to match ? Is it 0xFF18E7 by any chance ?

Is the syntax using HEX == actually valid ?

Have you looked at the examples that come with the library ?
