What could possibly be wrong with this code?

Please help me. I get an error and I don't know why. This is the error:

In function 'void loop()':

digitalWrite() is a void function
You probably want to use digitalRead()

Thank You very much. Sitting at 1 AM got to me. THanks again

Get's everyone. Glad it's fixed.
Happy Programming!

One more question if I may. Do You know what to do so that I don't have to wait each time for the reaction until these lines of code get through:lcd.print("1.STARTING"); //Wyświetlenie tekstu lcd.setCursor(0, 1); //Ustawienie kursora lcd.print("2.CAMERA"); //Wyświetlenie tekstu delay(3000); lcd.clear(); //Ustawienie kursora lcd.print("3.BRB"); //Wyświetlenie tekstu lcd.setCursor(0, 1); //Ustawienie kursora lcd.print("4.ENDING"); //Wyświetlenie tekstu delay(3000); lcd.clear(); //Ustawienie kursora lcd.print("5.DISPLAY"); //Wyświetlenie tekstu lcd.setCursor(0, 1); //Ustawienie kursora lcd.print("6.CONCERT"); //Wyświetlenie tekstu delay(3000);

The idea is that I want an instant reaction when I press one of the five buttons and if I don't press anything, this information just scrolls. Is that possible?

I run out of messages per day for a new user. If you can write how to do that I would be thankful. That's all for today from me.

Yes, but you haven't implemented cooperative multitasking. Your program style can only run one task at a time, now you want two. You have to use non-blocking code to do "more than one thing at a time".

You've got all the pieces, you just need to learn multitasking.
