Unable to understand error message

I am attempting to access a static variable from another sprite (Scoring)

Are you trying to access a static variable from another sprite or a script on that sprite? Please post your code. Here's an example: first script:

 public class script1 : $$anonymous$$onoBehaviour {
  
    public static int number;
  }

Now here is the other script that you needs to access script 1:

  public class Script2 : $$anonymous$$onoBehaviour {
     
  
     void Start(){
  
        script1.number = 10;
     }
  }

You access a static variable in a class this way:

      {class name}.{static member name}
 
 

  

So if this is the case:

      public class firstscript: $$anonymous$$onoBehaviour {
        public static bool Score = false;
      }
 

Then you access Score from any script like this:

       firstscript.Score  = true;
   if( firstscript.Score  == true) ...
