expected initializer before 'if'

#include <SPI.h>
#include “RF24.h”

RF24 radio(7,8);

unsigned long humid;
unsigned long celce;

void setup() {
Serial.begin(115200);
radio.begin();

radio.setPALevel(RF24_PA_LOW);
radio.startListening();
}

void loop()
if(radio.available()){

while (radio.available()) {
radio.read( &humid, sizeof(unsigned long) );
radio.read( &celce, sizeof(unsigned long) );
}
Serial.print("Humidity (%): ");
Serial.println(humid);
Serial.print("Temperature (C*): ");
Serial.println(celce);
}
}

What’s the problem!

Error

Functions ALWAYS start with a { and end with a }. You are missing the opening curly brace.

Oh my god thank you when I get anxious I get so bad on coding thnx
