Temperature sensor & LED

I am trying to get different LED's to turn on when the temperature reaches different temps.
anyone lend a hand?

//TMP36 Pin Variables
int temperaturePin = 0; //the analog pin the TMP36's Vout (sense) pin is connected to
//the resolution is 10 mV / degree centigrade
//(500 mV offset) to make negative temperatures an option

/*

  • setup() - this function runs once when you turn your Arduino on
  • We initialize the serial connection with the computer
    */
    void setup()
    {
    Serial.begin(9600); //Start the serial connection with the copmuter
    //to view the result open the serial monitor
    //last button beneath the file bar (looks like a box with an antenae)
    }

void loop() // run over and over again
{
float temperature = getVoltage(temperaturePin); //getting the voltage reading from the temperature sensor
temperature = (temperature - .5) * 100; //converting from 10 mv per degree wit 500 mV offset
//to degrees ((volatge - 500mV) times 100)
Serial.println(temperature); //printing the result
delay(1000);

}
{ pinMode(LEDPIN,OUTPUT); //waiting a second}
/*

  • getVoltage() - returns the voltage on the analog input defined by
  • pin
    */
    float getVoltage(int pin){
    return (analogRead(pin) * .004882814); //converting from a 0 to 1023 digital range
    }
    // to 0 to 5 volts (each 1 reading equals ~ 5 millivolts
    pinMode(ledPins [2],OUTPUT);
    pinMode(ledpins [4],OUTPUT);

if (analogueRead(0) < 22.75)
{
digitalWrite(2, High);
}
else (temperaturePin >22.75){
digitalWrite(LEDpin4, High);
}
