i need to get a value from a Sp

hi there in the sp i have this code  :

ALTER PROCEDURE dbo.MelayUpdateTotalquantity
            @ProKey varchar(50),
            @Total money output
      select Sum(Kamot) as Total from MelayActions where CodeParit=@ProKey

in the Form i have this code :

public bool GetSumTotal(string ProKey)
                  SqlParameter[] sp = new SqlParameter[2];

                  sp[0] = new SqlParameter("@ProKey",SqlDbType.VarChar,50);
                  sp[0].Value = ProKey;

                  sp[1] = new SqlParameter("@Total",SqlDbType.Money);

                  SqlDataReader dr = SqlHelper.ExecuteReader(strCnn,CommandType.StoredProcedure,"MelayUpdateTotalquantity",sp);
                  decimal sum =Decimal.Parse(sp["@Total"].Value.Tostring());
                  return true;            
i cant get the Total Value whit this line : decimal sum =Decimal.Parse(sp["@Total"].Value.Tostring());
how can i pull out the Total Value From the Sp to the sum variable ?

thanks ...

Try changing the sp like this

     select Set @Total = Sum(Kamot) from MelayActions where CodeParit=@ProKey
     RETURN @Total
