Touch Not Working

I have the following code for testing my buttons which will be used for player movement, but they are not registering hits. I have a main camera, then a second camera for orthographic projection. The hits are not being registered though.

 using UnityEngine;
 using System.Collections;
 
 public class mobileMove : MonoBehaviour {
 
     void Update()
     {
         if (Input.touchCount > 0) 
         {
             for (int i = 0; i < Input.touchCount; i++ )
             {
                 if ( this.guiTexture.HitTest (Input.GetTouch(i).position ))
                     {
                         if ( Input.GetTouch(i).phase == TouchPhase.Began )
                         {
                             Debug.Log("The touch is down on " + this.name );
                         }
 
                         if ( Input.GetTouch(i).phase == TouchPhase.Ended )
                         {
                             Debug.Log ("The touch has ended " + this.name );
                         }
                     }
                 }
     }
 }
 }
