Help with button (ArgumentOutOfRangeException: Index is less than 0 or more than or equal to the list count.)
i'm having a problem regarding on saving a name using an EVENT to my button.. i'm sure that i have done it correctly without error but my program is displaying this when i clicked my instantiated button..: (see attached image) 
really stucked in it haha. btw, the event OnClick.AddListener has no effect in my instatiated button, it does not display userAccounts as its OnClick event Here's my code, hope it'll help. thank you :)
public class ManageAccounts : MonoBehaviour
{
ConnectionDatabase cd;
// Use this for initialization
public GameObject accountContainer;
void Start ()
{
cd = Camera.main.GetComponent <ConnectionDatabase> ();
retrieveAccounts ();
}
private void retrieveAccounts ()
{
string query = "SELECT username FROM accounts;";
IDataReader reader = cd.SelectQuery (query);
while (reader.Read ()) {
GameObject account = Instantiate (accountContainer) as GameObject;
account.transform.SetParent (this.transform, false);
account.transform.GetChild (0).GetComponent <Text> ().text = reader.GetString (0);
account.GetComponent <UnityEngine.UI.Button> ().onClick.AddListener (() => userAccount (reader.GetString (0)));
}
}
public void userAccount (string account)
{
AccountMananger.Instance.accName = account;
SceneManager.LoadScene ("menu");
}
}

Solved.
i've just assign a string variable rather than accessing the reader.GetString(0) and placing it in the parameter of userAccounts
private void retrieveAccounts ()
{
string query = "SELECT username FROM accounts;";
IDataReader reader = cd.SelectQuery (query);
while (reader.Read ()) {
GameObject account = Instantiate (accountContainer) as GameObject;
account.transform.SetParent (this.transform, false);
string acc = reader.GetString (0);
account.transform.GetChild (0).GetComponent <Text> ().text = acc;
account.GetComponent <UnityEngine.UI.Button> ().onClick.AddListener (() => userAccount (acc));
}
}
