Is there something wrong with my combo script

 public class comboHits : MonoBehaviour
 {
 
     public Animator anim;
     public int noOfClicks = 0;
     float lastClickedTime = 0;
     public float maxComboDelay;
 
 
 
 
 
 
 
     // Start is called before the first frame update
     void Start()
     {
 
 
         anim = gameObject.GetComponent<Animator>();
 
 
 
     }
 
     // Update is called once per frame
     void Update()
     {
         
 
         if(Time.time - lastClickedTime > maxComboDelay)
         {
 
 
             noOfClicks = 0;
 
 
 
         }
 
         if (Input.GetKeyDown(KeyCode.Space))
         {
 
             lastClickedTime = Time.time;
             noOfClicks++;
             if(noOfClicks == 1)
             {
 
                 anim.SetBool("Attack1",true);
 
             }
 
             noOfClicks = Mathf.Clamp(noOfClicks, 0, 2);
 
         }
 
 
 
 
 
     }
 
 
 
     public void return1()
     {
 
         if (noOfClicks >= 2)
         {
 
             anim.SetBool("Attack2", true);
 
 
 
         }
         else
         {
 
             anim.SetBool("Attack1", false);
             noOfClicks = 0;
 
         }
 
     }
     public void return2()
     {
 
         if (noOfClicks >= 2)
         {
 
             anim.SetBool("Attack2", true);
 
 
 
         }
         else
         {
 
             anim.SetBool("Attack1", false);
             noOfClicks = 0;
 
         }
 
     }
 
 }
