'No overload for method' when attatching fmod event to animation event

[MattLightbound]

using UnityEngine;
using System.Collections;

public class Playersounds : MonoBehaviour {

    public void PlayerFootsteps () 
    {
        FMOD_StudioSystem.instance.PlayOneShot("event:/PLayerSteps", transform.position);
    }
}
