Why is the command function not being called on the client?

I am not sure why the CmdSpawn code isn't being called. It doesn't print the dropLocation in the console but it spawns a block at 0,0,0. The code works fine on the host but not on the client. I have been struggling on this same thing for about 2 weeks and I am sick of it. Please help, here is the current code:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Networking;

public class Shooting : NetworkBehaviour {

 [SerializeField] public Transform shootLocation;
 [SerializeField] public GameObject cannonBall;
 [SerializeField] public float shootingSpeed;
 [SerializeField] public static int blocks;
 [SerializeField] public GameObject cube;
 [SerializeField] public static Vector3 dropLocation;

 void Start () {
     blocks = 5;
 }
 
 void Update () {

     if (Input.GetMouseButtonDown(0))
     {
         if (blocks > 0)
         {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             RaycastHit hit;
             if (Physics.Raycast(ray, out hit))
             {
                 if (hit.transform.name != "null" && hit.transform.name != "wall")
                 {
                     dropLocation = new Vector3(hit.point.x, hit.point.y + 1.75f, hit.point.z);
                     CmdSpawn();
                     print(blocks);
                 }
             }
         }
         else
         {
             CmdFire();
         }
     }
 }

 [Command]
 void CmdSpawn()
 {
     print(dropLocation);
     blocks = blocks - 1;
     GameObject block = Instantiate(cube, dropLocation, Quaternion.identity);
     NetworkServer.Spawn(block);
 }

 [Command]
 void CmdFire()
 {
     var shell = Instantiate(cannonBall, shootLocation.position, shootLocation.rotation);
     shell.GetComponent<Rigidbody>().velocity = shell.transform.forward * shootingSpeed;
     NetworkServer.Spawn(shell);
 }

}
