getting the select value

CroNix,
thank you very much you were very helpful.
and now its working fine.
and the problem was in the name of the select ('ID') which is the same name of the db col name i think its shouldn't be the same, changing it solve the problem.
btw, none of the code i use is wrong specially set_value()

best regards.
