expected unqualified-id before 'if' error, PLEASE HELP!

I am new to programming with arduino so I am sorry if it is something obvious that I missed.

whenever I try to compile my code I get the error “expected unqualified-id before ‘if’”, I cannot seem to resolve this issue on my own, maybe someone more experienced can help. This is for a flame sensor module

int sensor = A0;
int sensorValue = 0;
int red = 8; // Multi color LED used to show the state of the flame. 
int green = 9;
int blue = 10;

void setup()
{
  Serial.begin(9600);
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}

void loop() {
  sensorValue = analogRead(flame);
  Serial.println(sensorValue);
}
  
  if(sensorValue > 800) {
  digitalWrite(green, HIGH);
  }
  
  if(sensorValue < 800) {
  digitalWrite(blue, HIGH);
  }
  
  if(sensorValue > 400) {
  digitalWrite(blue, HIGH);
  }
  
  else  {
  digitalWrite(blue, LOW);
  }
  
  if(sensorValue < 400) {
  digitalWrite(red, HIGH);
  }
  delay(50);
}

Everything after:
if(sensorValue > 800) {
. . .
is not inside of the loop() function.

Check the { } placement in loop()
:wink:
