Can't execute my first script

I want to run the script in the scene to see if it is doing it ok in console, but when I press play it says "All compiler errors have to be fixed before you can enter playmode"

It because the code or what?, IDK what to do

here's the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class comportamiento : MonoBehaviour {

public string playerName = "Luis Robles";
public int playerScore = 0;
private int maxScore = 120;
public int playerAge = 0;

// Start is called before the first frame update
void Start(){

Debug.Log(playerScore + 12);


}

// Update is called once per frame
void Update(){
if (Input.GetKeyUp(GetKeyCode)) BirthDay();
}


void BirthDay() {

Debug.Log(playerAge + 1);
}

}

 

Your code editor should have brought attention to these code errors as soon as you typed them. If you didn't notice the usually red squiggly lines in your code editor then the console will include the exact line numbers where it believes the problem is in your code (basically the point where the compile fails, which is either on the exact line or a line or two later but still really close).
