error CS1525: Unexpected symbol `(', expecting `)', `,', `;', `[', or `='

Hello, I`m new to C# and I`ve been following some tutorials on the UI in 4.6 and in my script I get this error: Assets/Scripts/Menu/Functions.cs(19,38): error CS1525: Unexpected symbol (', expecting )', ,', ;', [', or ='

Here is my script:

 using UnityEngine;
 using System.Collections;
 
 public class Functions : MonoBehaviour {
     
     public GameObject Options;
     public GameObject Main;
     
     public void OptionsButton()
     {
         SendMessageOptions.SetActive (true);
         Main.SetActive (false);
     }
     
     public void SaveClose()
     {
         StartCoroutine ("waitTimer", 1);
         
         IEnumerator waitTimer(float waitTime)
         {
             yield return new WaitForSeconds(waitTime);
         }    
     }
