Analog sensors reading and updating to Blynk Server

Need Help With My Project
1

I am using Arduino Due. I am connecting ESP8266-01 for WiFi through Serial1 of Arduino Due. I want to read two sensors from A0,A1 and update them to Blynk Server for every 3 seconds continuously. When I am compiling, I am getting error as " ‘gg’ was not declared in this scope ". Can someone help me to get rid of that error and get desired output.

#define BLYNK_PRINT Serial
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

BlynkTimer timer;

#define EspSerial Serial1
#define ESP8266_BAUD 115200

char auth[] = "xxxx";
char ssid[] = "ssid";
char pass[] = "pwd";

ESP8266 wifi(&EspSerial);


void setup() 
{
  Serial.begin(9600);
  EspSerial.begin(ESP8266_BAUD);
  delay(10);
  Blynk.begin(auth, wifi, ssid, pass);
  delay(10);
    
 pinMode(A0,INPUT);   
 pinMode(A1,INPUT);   

 timer.setInterval(3000L,gg);
 timer.setInterval(3010L,hh);
 
}

void loop() 
{
int a=Serial.read(A0);
int b=Serial.read(A1);
Blynk.run();
timer.run();
}

void gg()
(
Blynk.virtualWrite(V1,a);
}

void hh()
(
Blynk.virtualWrite(V2,b);
}

void gg()
( <<<<< wrong type of bracket
Blynk.virtualWrite(V1,a);
}
