now my mind is mush....appreciate the willingness to help here is my latest attempt which kicked back errors

int SOUND = 10;
int ALERTLIGHT = 9;
int BUNKLIGHT = 8;
int SPEAKER = 7;
int alert = 2;

unsigned long SOUNDOnTIME;
unsigned long ALERTOnTIME;
unsigned long BUNKLIGHTOnTIME;
unsigned long SPEAKEROnTIME;

bool SOUNDOn;
bool ALERTOn;
bool BUNKLIGHTOn;
bool SPEAKEROn;





void setup() {
  // put your setup code here, to run once:

  Serial.begin(9600);
  pinMode(SOUND, OUTPUT);
  pinMode(ALERTLIGHT, OUTPUT);
  pinMode(SPEAKER, OUTPUT);
  pinMode(BUNKLIGHT, OUTPUT);
  pinMode(alert, INPUT);


  SOUNDOn = false;
  ALERTOn = false;
  BUNKLIGHTOn = false;
  SPEAKEROn = false;
}

void loop() {
  if (digitalRead(alert) == HIGH) {
    digitalWrite(SOUND, HIGH);
    SOUNDOn = true;
    SOUNDOnTIME = millis(3000);
  }
