Speaker,SD, Ultrasonic Sensor and LED help

Projects Programming

Hello

I am making a device that when the user puts their hand less than 20 cm away from either Ultrasonic sensor an LED lights up and music starts playing from an SD card as a wav file, then after a certain amount of time the music stops and the LED switches off.

I have coded each individual bit successfully but when i put it all together it just lists a load of errors.

Attached is the code I am trying to debug but i am completely stuck. any help would be much appreciated.

Thanks

{
  void SonarSensor(int trigPin, int echoPin)
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
etc, etc

This is not how you write a function
Compare it with the loop() function

void loop()
{
  SonarSensor(trigPin1, echoPin1);
  RightSensor = distance;
  SonarSensor(trigPin2, echoPin2);
etc, etc
