Incorrect Syntax Near [SQL UPDATE COMMAND] &> Cmd.ExecuteNonQuery()

Please let me know what is wrong with my code below. I keep getting the "Incorrect syntax near 'UpdateInfoByAccountAndFullName'." error when I execute cmd.executenonquery.  I highlighted the part that errors out.  Thanks a lot. 
 ---------------------------------------------------------------------------------------------------------------------------
         public bool Update(
                string newaccount, string newfullname, string rep, string zip,
                string comment, string oldaccount, string oldfullname
            )
        {
            SqlConnection cn = new SqlConnection(_connectionstring);
            SqlCommand cmd = new SqlCommand("UpdateInfoByAccountAndFullName", cn);
            cmd.Parameters.AddWithValue("@newaccount", newaccount);
            cmd.Parameters.AddWithValue("@newfullname", newfullname);
            cmd.Parameters.AddWithValue("@rep", rep);
            cmd.Parameters.AddWithValue("@zip", zip);
            cmd.Parameters.AddWithValue("@comments", comment);
            cmd.Parameters.AddWithValue("@oldaccount", oldaccount);
            cmd.Parameters.AddWithValue("@oldfullname", oldfullname);

            using (cn)
            {
                cn.Open();
                return cmd.ExecuteNonQuery() > 1;
            }
        }
