I need to convert a text (numbers only) i downloaded with WWW and then convert it to a int. Here is my current code but it is not working:
using UnityEngine;
using System.Collections;

public class FetchXP : MonoBehaviour {
public GUISkin GUISkin;
public string url = "url";
	IEnumerator  Start (){
		PlayerPrefs.DeleteKey("xp");
		WWWForm form = new WWWForm();
		form.AddField( "username", PlayerPrefs.GetString("Username"));
		WWW download = new WWW( url, form );
		yield return download;
		if((!string.IsNullOrEmpty(download.error))) {
			print( "Error downloading: " + download.error );
		} else {
			Debug.Log(download.text);
			int.Parse(download.text);
			PlayerPrefs.SetInt("xp", download.text);
		}
	}

Errors:

1.(18,37): error CS1502: The best overloaded method match for `UnityEngine.PlayerPrefs.SetInt(string, int)’ has some invalid arguments

2.(18,37): error CS1503: Argument #2' cannot convert string’ expression to type `int’

int parsedInt = int.Parse(download.text);
PlayerPrefs.SetInt(“xp”, parsedInt );
