Invalid Layer Index?

OK this is weird, I have two animations that I start from a C# script, the animations are fine and they work OK but one of them will not play in my UI interface set up? I get the following error:

Invalid Layer Index UnityEngine.Animator:Play(String) ScannerAdjustmanager:StartScannerLights() (at Assets/ScannerAdjustmanager.cs:42) UnityEngine.EventSystems.EventSystem:Update()

In my inspector I have the Animator Unchecked and my C# script is supposed to activate them when I press a UI button, but only one of them works, and I get that error message above? I'll post my script just incase anyone can see something I'm missing.

 using UnityEngine;
 using System.Collections;
 
 public class ScannerAdjustmanager : MonoBehaviour {
 
     //Reference to Animations
     public GameObject ScannerLightAni;
     public GameObject BlueLEDsAni;
 
     //Audio Clip References
     public AudioClip Scanner;
 
     //animator reference
     private Animator anim;
 
     void Start () {
         //unpause the game on start
         //Time.timeScale = 1;
         //get the animator component
         anim = ScannerLightAni.GetComponent<Animator>();
         anim = BlueLEDsAni.GetComponent<Animator>();
         //disable it on start to stop it from playing the default animation
         //anim.enabled = false;
     }
 
 
 
     public void  GoAbort(){
         StartCoroutine(LoadAfterDelay("ThreeD_Overview"));
     }
     
     IEnumerator LoadAfterDelay(string levelName){
         yield return new WaitForSeconds(0.5f); // wait 1 seconds
         Application.LoadLevel(levelName);
         
     }
 
     //Start Scanner Animations
     public void  StartScannerLights(){
         //StartCoroutine(AutoDoorOutR());
         anim.enabled = true;
         anim.Play("ScannerAdjustAnimation");
     }
 
     //Start LEDs Animations
     public void  StartLEDLights(){
         //StartCoroutine(AutoDoorOutR());
         anim.enabled = true;
         anim.Play("ScannerBlueLEDsAni");
 
         //Audio Play
         audio.clip = Scanner;
         audio.loop = true;
         audio.Play();
     }
 }
