I have a wizard like this: http://jsfiddle.net/rniemeyer/FyuSD/ when i click button next data of current step are send to the server (the function to send data its not display in this link ) in the server i have an action like this:

[HttpPost]
    public ActionResult SocialNetworkChoice(string[] selectedSocialNetwork)
    {
        if (selectedProduct!= null)
        {
          // check if the user got a social account linked in for all the selected networks
          // and redirect to the link account page
          ....
            if (q.Count() > 0)
            {
                return RedirectToAction("LinkAccount", "Account", new LinkAccountModel() { ProviderName = q.First() });
            }

            else
            {....}

          }

in the first step i have two checkbox for two social networks, when a user check ckeckbox data its send to the action SocialNetworkChoice. if (q.Count() > 0) the view for action "LinkAccount" doesn't display and the wizard pass to the second step

How can to solve this probleme if (q.Count() > 0) redirect to LinkAccount (View) else to second step
