Application OpenUrl 'Unexpected Symbol Application'

 using UnityEngine;
 using System.Collections;
 
 public class buy_Me : MonoBehaviour {
 
     public Texture2D button1;
     
     void Start () {
         guiTexture.texture = button1;
     }
     void Update () {
         if (guiTexture.HitTest(touch.position) && touch.phase == TouchPhase.Ended
             Application.OpenURL("market://details?id=com.cjggaming.pob1");
             }
 }

Why on earth is application causing this error?
