"'microsecondsToCentimeters' was not declared in this scope" error

Development Tools IDE 1.x

I keep getting the following error "'microsecondsToCentimeters' was not declared in this scope". I'm still relatively new to arduino but I have no idea where the error might be in this one.

This is the part of the programm spitting the error out.

pinMode(pingPin, OUTPUT);
digitalWrite(pingPin, LOW);
delayMicroseconds(2);
digitalWrite(pingPin, HIGH);
delayMicroseconds(10);
digitalWrite(pingPin, LOW);

pinMode(inPin, INPUT);
duration = pulseIn(inPin, HIGH);

cm = microsecondsToCentimeters(duration);

Serial.println(cm, DEC);
delay(100);

int sensorValue4 = cm;

Serial.println(sensorValue4);
delay(1);

if(sensorValue0 < 270 && sensorValue4 > 12)
{
digitalWrite(7, HIGH);
}

else
{
digitalWrite(7, LOW);

digitalWrite(4, HIGH);
delay(500); t
digitalWrite(4, LOW);
delay(500);
}
