printing ASCII and 3 variables to RS232 to control video mixer

trying piece together from other code.. I don't think im referencing my values correctly when trying to do the serial.print.

am I even close?

/*

  • SerialOutput sketch
  • Print numbers to the serial port
    */
    void setup()
    {
    Serial.begin(9600); // send and receive at 9600 baud
    }
    int potPin = 2; // select the input pin for the potentiometer
    int val2 = 0; // variable to store the value coming from the sensor
    int potPin = 3; // select the input pin for the potentiometer
    int val3 = 0; // variable to store the value coming from the sensor
    int potPin = 4; // select the input pin for the potentiometer
    int val4 = 0; // variable to store the value coming from the sensor

void loop()
{
val = analogRead(potPin); // read the value from the sensor
Serial.print("stxHPI:(val2),(val3),(val4)");

}
