theres no error report but the input key won't perform the action it's supposed to,theres no error showing yet the key won't perform the desired action

public class LOCATION : MonoBehaviour { public Transform position;

 public string Source;
 public string Conduit;
 public string Implement;

 private float Healthmax;
 public float Health;

 void Start()
 {
     Vector3 pos = transform.position;
     transform.position = new Vector3(x: Ndegree + 150, y: Edegree + 250, z: 214);

     Power = Strength + Chakra + Spirit + Speed + Dexterity + Reflex + Intel + Wits + Mind + Endure + Resist + Shell;
     Health = (Endure * 10) + (Resist * 2) + (Chakra * 10);
     Stamina = (Dexterity * 10) + (Chakra * 2) + (Resist * 2);
     Energy = (Spirit * 10) + (Mind * 5);
     
 }

 void Fixedupdate ()
 {
     if (Input.GetKey("a"))
     {
         Health= (Endure * 10) + (Resist * 2) + (Chakra * 10);
         Staminamax = (Dexterity * 10) + (Chakra * 2) + (Resist * 2);
         Energymax = (Spirit * 10) + (Mind * 5);
     }
     
 }

}

PS: the bottom health is supposed to be HealthMax but for debuging purposes... also this program is defining about 50 other character stats, though i don't know if that's the issue since the Update part won't even return a debug.log text to me.
