i need help with the code below, i want to program it on the pro-mini chip but so far im finding it difficult to get it right.

#include <VirtualWire.h>

const int trigPin = 2;

const int echoPin = 4;

char Distance[4]; void setup() {

Serial.begin(9600);

vw_setup(2000);

}

void loop() {

int duration, distance, cm;

pinMode(trigPin, OUTPUT);

digitalWrite(trigPin, LOW);

delayMicroseconds(2);

digitalWrite(trigPin, HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

pinMode(echoPin, INPUT);

duration = pulseIn(echoPin, HIGH);

distance=duration*34/200000;

//Convert metre to cm

cm = distance*100

Serial.print(cm);

Serial.print("cm");

Serial.println();

delay(100);
//Convert integer value to character value

itoa(cm,Distance,10);

digitalWrite(13, true); // Turn on a light to show transmitting

vw_send((uint8_t *)Distance, strlen(Distance));

vw_wait_tx(); // Wait until the whole message is gone

digitalWrite(13, false); // Turn off a light after transmission

delay(200);

}

  cm = distance*100

    Serial.print(cm);

Semicolons on the ends of statements are NOT optional.
