Login User Roles in Jquery MVC

Hi,

I have the following code in my controller for login in my MVC. I am trying to use different users to be able to login and be redirected to different pages on login. When I use the code below I get the following error:

Value cannot be null.
Parameter name: providerUserKey



How do I correct this?

private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
private MembershipUser CurrentUser;
private string[] UserRoles;
private FxDataClassesDataContext dcfx = new FxDataClassesDataContext();
private object UserName;
//
// GET: /Account/Index
////private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

public ActionResult Index()
{

return View();
}

//
// GET: /Account/LogOn

[AllowAnonymous]
public ActionResult LogOn()
{
return View();
}

[AllowAnonymous]
[HttpPost]
public ActionResult LogOn(LogOnModel model, string returnUrl)
{

MembershipUser currentUser = Membership.GetUser(UserName);
string UserID = currentUser.ProviderUserKey.ToString();

UserRoles = Roles.GetRolesForUser();

if (UserRoles.Length > 0)
{
if (User.IsInRole("Shipper"))
{
// Find Shipper data
var objShipper = (from s in dcfx.FxShippers
where s.Shipper_USerName == CurrentUser.UserName
select s).First();

Session.Add("ShipperID", objShipper.Shipper_ID);

if (log.IsInfoEnabled)
{
log.Info("Username: " + CurrentUser.UserName + ", Role: " + UserRoles[0] + ", Shipper ID: " + objShipper.Shipper_ID.ToString());
}

// Redirect to Shipper Portal page
Response.Redirect("Shipperportal.cshtml");
}
else if (UserRoles[0] == "Transporter")
{
// Find Transporter data
// Find Shipper data
var objTransporter = (from s in dcfx.FxTransporters
where s.Transporter_UserName == CurrentUser.UserName
select s).First();

Session.Add("TransporterID", objTransporter.Transporter_ID);

if (log.IsInfoEnabled)
{
log.Info("Username: " + CurrentUser.UserName + ", Role: " + UserRoles[0] + ", Transporter ID: " + objTransporter.Transporter_ID.ToString());
}

// Redirect to Transporter Portal page
Response.Redirect("TransporterPortal.cshtml");
}
else if (UserRoles[0] == "FxAdmin")
{
// Redirect to Transporter Portal page
Response.Redirect("");
}

return View();

}
