Rotating menu with 360 controller.

Hey. I'm trying to tweak my game to use controller input instead of mouse and keyboard. When I click an arrow in the menu scene it rotates 90 degrees in the arrows direction. I want it so that when the player pulls the trigger the menu rotates 90 degrees depending on the trigger pulled. For some reason it reads the input but makes the makes the menu spin rapidly for no reason.

void Update() {

     //Debug 360 controller triggers
     float rightTriggerPullAmount = Input.GetAxis ("Fire1");
     float leftTriggerPullAmount = Input.GetAxis ("Fire2");
     Debug.Log (leftTriggerPullAmount.ToString ());
     Debug.Log (rightTriggerPullAmount.ToString ());

     if (rightTriggerPullAmount == 1.0f) 
     {
         float currentAngle = Camera.main.transform.rotation.eulerAngles.y;
         
         if(Mathf.Abs(totalRotation) < Mathf.Abs(rotateDegreesAmount))
         {
             float rotateAmount = Time.deltaTime * degreesPerSecond;
             if(totalRotation + rotateAmount > 90){
                 rotateAmount = 90-totalRotation;
             }
             Camera.main.transform.rotation = Quaternion.AngleAxis(currentAngle + rotateAmount, Vector3.up);
             totalRotation += rotateAmount;

             Debug.Log("Rotation Amount: " + rotateAmount.ToString());
         }
         
         //Debug.Log(totalRotation);            
     }

     if (isLeftArrowClicked ) 
     {  


         float currentAngle = Camera.main.transform.rotation.eulerAngles.y;
         
         if(Mathf.Abs(totalRotation) < Mathf.Abs(rotateDegreesAmount))
         {
             float rotateAmount = Time.deltaTime * degreesPerSecond;
             if(totalRotation + rotateAmount > 90){
                 rotateAmount = 90-totalRotation;
             }
             Camera.main.transform.rotation = Quaternion.AngleAxis(currentAngle - rotateAmount, Vector3.up);
             totalRotation += rotateAmount;
         }    
         
         Debug.Log("Total rotation: " + totalRotation.ToString());
         
         isRightArrowClicked = false;            
     }
     
     if (isRightArrowClicked)
     {

         float currentAngle = Camera.main.transform.rotation.eulerAngles.y;
         
         if(Mathf.Abs(totalRotation) < Mathf.Abs(rotateDegreesAmount))
         {
             float rotateAmount = Time.deltaTime * degreesPerSecond;
             if(totalRotation + rotateAmount > 90){
                 rotateAmount = 90-totalRotation;
             }
             Camera.main.transform.rotation = Quaternion.AngleAxis(currentAngle + rotateAmount, Vector3.up);
             totalRotation += rotateAmount;

             Debug.Log("Rotation Amount: " + rotateAmount.ToString());
         }

         //Debug.Log(totalRotation);
         
         isLeftArrowClicked = false;
         
         //Debug.Log(camYRot.ToString());
     }
