Can not access the class RandomSoundPlayer

So everything was going really well until the part in the video where we use the class RandomSoundPlayer as a type in both the bird and player movement scripts. Inside of the RandomSoundPlayer I can access the class, but in the PlayerMovement and BirdMovement Script Files whenever I type RandomSoundPlayer it is underlined in red. I'm using visual studio if that helps. Here is my RandomSoundPlayer Code:

using UnityEngine; using System.Collections; using System.Collections.Generic;

public class RandomSoundPlayer : MonoBehaviour { private AudioSource audioSource; [SerializeField] private List<AudioClip> soundClips= new List<AudioClip>(); [SerializeField] private float soundTimerDelay = 3f; private float soundTimer;

// Use this for initialization
void Start () {
    audioSource = GetComponent<AudioSource>();

}

// Update is called once per frame
void Update () {
    //increment timer to count up to restart
    soundTimer = soundTimer + Time.deltaTime;
    //if timer reaches delay
    if (soundTimer >= soundTimerDelay)
    {
        //Reset the timer

        soundTimer = 0f;

        //Choose a random sound
        AudioClip randomSound = soundClips[Random.Range(0,soundClips.Count)];

        //And play sound
        audioSource.PlayOneShot(randomSound);
    }
}

}
