Project Not working after 1 day and no changes.

I made this code the other day and it worked perfectly. I came back the next morning and all of a sudden it doesn't, and I can't figure out why.

public class GameManager : MonoBehaviour { public int values; public bool papers; public bool rock; public bool scisor;

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

 }

 // Update is called once per frame
 void Update()
 {
     if (Input.GetKeyDown(KeyCode.E))
     {
         papers = true;
     }
         

 }

 

} It works when I put in "rock" But whenever I type in "papers" and "scisors" It doesn't become true in the inspector.
