Question, why do I get NullReferenceException error in this code?

How can I correct this.

Thank you.


        string r = (string)(" ");
        r = Session["Region"].ToString();     // stepping shows r = "Region 1"

      if (IsPostBack)
            if (Session["Region"] != null)
                MasterPage myMaster = Master as MasterPage;
                DropDownList regionDropDownList = (DropDownList)myMaster.FindControl("cboRegion");
                regionDropDownList.Text = Session["Region"].ToString();   //  <---  NullReferenceException  **********
