saving a word document to a data base

Hello experts I have a new problem.

 I have a web app that stores various text boxes and checkboxes to a database. I need to be able to allow the users to save word documents as well. This is my problem.

In my database (tbl_info) I have a fleld named (ConsentDocument) it is listed as a Data Type of varbinary(1024) and it is set to allow nulls in case the field is not used/required per user case by case basis.

my stored proc looks like this
ALTER PROCEDURE [dbo].[P_sp_DetailedResearchSummary_PP]
      @parameter1 int = 5,
      @parameter2 datatype OUTPUT
      @summary      varchar(500),
      @purpose      varchar(500),
      @methods      varchar(500),
      @schoolBased varchar(500),
      @listofSurveys      varchar(500),
      @surveyDoc      varbinary(1024),
      @international      varchar(500),
      @user nvarchar(10),
      @pass nvarchar(20)

      /* SET NOCOUNT ON */
      UPDATE tbl_info
      SET      ResearchSummary = @summary,
            ResearchPurpose = @purpose,
            MethodsAndProcedures = @methods,
            SchoolBasedResearch = @schoolBased,
            ListofSurveys = @listofSurveys,
            SurveyDoc = @surveyDoc,
            InternationalResearch = @international
      WHERE ParkIDIRB = @user
      AND ParkIRBPass = @pass

and then my C# code behind looks like this... (yes I know its currently commented out : ) )

  //if (ddlFactStafStuQuestion.SelectedValue == "Yes")
            //    SqlConnection con = new SqlConnection(@"Data Source=x;Initial Catalog=Wdb_IRB;User Id=Ix;Password=x;");
            //    con.Open();
            //    SqlCommand cmd = new SqlCommand("P_sp_DetailedResearchSummary_PP", con);
            //    cmd.CommandType = CommandType.StoredProcedure;
            //    cmd.Parameters.AddWithValue("@summary", TBResearchSummary.Text);
            //    cmd.Parameters.AddWithValue("@purpose", TBPurpose.Text);
            //    cmd.Parameters.AddWithValue("@methods", TBMethods.Text);
            //    cmd.Parameters.AddWithValue("@schoolBased", TBSchoolBasedResurch.Text);
            //    cmd.Parameters.AddWithValue("@listofSurveys", TBMeasures.Text);
            //    cmd.Parameters.AddWithValue("@surveyDoc", FULDocument1.FileContent);
            //    cmd.Parameters.AddWithValue("@user", TBParkID.Text);
            //    cmd.Parameters.AddWithValue("@pass", TBParkIRBPass.Text);
            //    cmd.ExecuteNonQuery();
            //    con.Close();


Can anyone tell me what in the world I am doing wrong or how to complete this task please?

            testlbl.Visible = true;

            SqlConnection con = new SqlConnection(@"Data Source=x;Initial Catalog=Wdb_IRB;User Id=x;Password=x;");
              SqlCommand cmd = new SqlCommand("InsertFile", con);
                cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@FileName", FileUpload4.PostedFile.FileName);
            cmd.Parameters.Add(new SqlParameter("@Extension", FileUpload4.PostedFile.GetType()); //"Extension of Uploaded File"));
            cmd.Parameters.Add(new SqlParameter("@Content", FileUpload4.PostedFile.ContentType(); //"byte array (byte[]) of uploaded file"));
