STOP CROSS-POSTING.

please check whether the given code is correct

The compiler already told you.

This compiles.

#include <Servo.h>
Servo myservo1;
Servo myservo2;
const int pingPin=2;
long duration, distanceCm=0;
long distanceFront=0;
void setup ()
{
  myservo1.attach (9);
  myservo2.attach (10);
}
void loop ()
{
  pinMode(pingPin,OUTPUT);
  digitalWrite(pingPin,LOW);
  delayMicroseconds(2);
  digitalWrite(pingPin,HIGH);
  delayMicroseconds(5);
  digitalWrite(pingPin,LOW);
  pinMode(pingPin,INPUT);
  duration=pulseIn(pingPin,HIGH);
  //distanceInches=duration/73/2;
  distanceCm=duration/28.6/23/2;
  //Serial.print(distanceInches);
  //Serial.print("in,");
  //Serial.print(distanceCm);
  //Serial.print("cm");
  //Serial.println0;
  delay (100);
  distanceFront=distanceCm;
  if(distanceFront>1){
    if(distanceFront>10){
      myservo1.write(0);
      myservo2.write(180);
      delay(100);
    }
    else{
      myservo1.write(0);
      myservo2.write(0);
      delay(100);
    }//else
  }//if
}//loop

Please study it, and note the differences between it and your code.
