In my code Data's find compares the argument with the values[0],
where values[] is a DataInfo array. Therefore, I think, it should
match with Flight number and in my database there is no such
a number.

Hi Andras,

Same with mine!

Therefore, I think, it should
match with Flight number and in my database there is no such
a number.

Yeah, you are right! i agree with you that the argument toMatch should match with some Flight number! In my db.db file, THERE IS FLIGHT NUMBER. a typical output of a record is:
suncerfiy.db.DataInfo@2f6684recordNumber = 1
Fields: Name = Flight number value = SA001
Name = Origin airport value = SFO
......
I did wrong the first time for i followed Sun's instruction and use a record number as the argument which always "find" a null result. When Flight number value, say SA001, is used as "toMatch" string, the expected result comes out!
Thus, sun's wording is not quite right when it says "For this assignment, the key field is the record number field...@param toMatch The key field value to match upon for a successful find".
Anyone please correct me if i missed something here. Andras, thank you and good luck!
cheers!
Daniel
