Idle animation not working

I have a 2d sprite that I'm trying to animate using the demo version of ex2d. I can get movement to work, and I can get an idle animation to work, but I can't get them both working at the same time. This is what I thought would make most sense for getting them both to work, but now only idle animation plays, even if I move left or right.

 if (Input.GetAxisRaw("Horizontal").Equals (-1))
         {    
             gameObject.transform.eulerAngles = new Vector3(0, 180, 0);
             
             if (isPlayingAnim==false)
             {
                 spriteAnimation.Play("BG_Moving");
                 isPlayingAnim=true;
             }
         }
         else if (Input.GetAxisRaw("Horizontal").Equals(1))
         {
             gameObject.transform.eulerAngles = new Vector3(0, 0, 0);
             
             if (isPlayingAnim==false)
             {
                 spriteAnimation.Play("BG_Moving");
                 isPlayingAnim=true;
             }
         } 
         else if (!Input.anyKey)
         {
             if (isPlayingAnim==false)
             {
                 spriteAnimation.Play("BG_Idle");
                 isPlayingAnim=true;
             }
         }

Any thoughts/help as to how to get this working would be greatly appreciated.
