`string' does not contain a definition for `error' and no extension method `error' of type `string' could be found (are you missing a using directive or an assembly reference?)

Hi gang were do i Assign error to so unity knows if their is an error?

IEnumerator GetUserAccount(int Gold, string name)
		{
		//all acount items, here...
		string hash = MD5.Md5Sum(secretKey);
		string Account_get = GetAccount + "name=" + name + "hash=" + hash;

			yield return Account_get;
			
			if (Account_get.error != null)
			{
			print("Their was an error getting Account, Account dose not Exist" + Account_get.error);
			}
			else
		    {
				//DISPLAY EACH STRING ITEM AS SEPRET TEXT....
			gameObject.GetComponent<GUIText>().text = Gold.ToString();
			}
		}

best overloaded method error? i have assigned callback function in the script. to get id data

void Start()
		{
		FB.API("/me?fields=id", Facebook.HttpMethod.GET, APICallback);
		StartCoroutine(GetUserAccount());
		}

I not sure, but it seems to me that you are trying to do a web request with a string…

maybe you should try a things like that :

WWW Account_get = new WWW("name=" + name + "hash=" + hash);

yield return Account_get;
         
if (Account_get.error != null)
...

I hope this help
