well this is really the first time i have tried to program codes and stuff like this so bear with me. this is what i managed to do from what you guys have been saying but when i click to check it it says that
in function 'void loop()':
'holdDelay' cannot be used as a function

 int ledPin1 = 2;                  
int ledPin2 = 3;                
int ledPin3 = 4;
int ledPin4 = 5;
int ledPin5 = 6;
int ledPin6 = 7;
int ledPin7 = 8;
int inputPin = 10;
int val = 0;
int   holdDelay(500);
void setup()  {                  




  pinMode(ledPin1, OUTPUT);        
  pinMode(ledPin2, OUTPUT);      
  pinMode(ledPin3, OUTPUT);
  pinMode(ledPin4, OUTPUT);
  pinMode(ledPin5, OUTPUT);
  pinMode(ledPin7, OUTPUT);
  pinMode(ledPin6, OUTPUT);
  pinMode(inputPin, INPUT);

  }

 void loop  () {
  long endTime; 
endTime = millis() + 500;
while(endTime>millis()) {
  val = digitalRead(inputPin);
  if (val == HIGH)
