question about the sample128 in UM-B-003

On page 19: status = attmdb_att_set_value(sample128_1_char_hdl, sizeof(sample128_1_char),(uint8_t *)&sample128_1_char);

the parameter sample128_1_char_hdl is right ?

like: status = attmdb_att_set_value(char_hdl, sizeof(sample128_2_char),(uint8_t *)&sample128_2_char); on page 20.
