SendMessage not working While Animator is Enabled

I have been using SendMessage to handle a simple inventory system. However objects with an Animator on them will no longer receive the message(I am assuming this based on the fact that the Debug.Log message doesn't get sent). If I comment out the Animator code and disable the component then the message will again be received

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class Tarren : MonoBehaviour {
 
     private GUIText Conversation;
     //private Animator TalkingAnim;
     private Inventory script;
     private bool bool1 = false;
 
     void Start () 
     {
         //TalkingAnim = GetComponent<Animator>();//Gets the Animator
         Conversation = GameObject.Find ("Conversation").GetComponent<GUIText> ();
         script = GameObject.Find("Lizzie").GetComponent<Inventory>();
         Debug.Log ("Tarren");
     }
     
 
     void Update () 
     {
     
     }
 
     void InteractionStart (){
         Debug.Log ("Tarren");  // This Doesn't Show Up in the Log
         //TalkingAnim.SetBool ("TalkingBool",true);
         if (script.Items.Contains ("Sheet Music") == false) {
         
                         if (bool1 == true) {
             
                                 script.Items.Add ("Sheet Music");
                                 Conversation.text = "Hello";
                         }else    
                         {
                             bool1 = true;
                             Conversation.text = "Hello2";
                         }
                 } else 
                     Conversation.text = "Hello3";
 
 }
 
     void InteractionEnd() 
         {
         Conversation.text = "Goodbye";//Changes the On screen text to Goodbye
         //TalkingAnim.SetBool ("TalkingBool", false);
         }
 
 }
 
   

I am very confused and have no idea how to fix this. All other objects without Animators work fine. Any help would be greatly appreciated
