>I'm writting an application, but i can't pass this point. One of my forms uses a document id that must be the some in other table. After the user confirm all the data the program must write the new record in the first table and write the new value in the other table. This seems very simple but in fact i can't make it over. Can someone give-me a hint ?? TIA.

what is it exactly that u are trying to do
do these tables have a relation set
did u set refrential rules ? do u have problems with buffering?
etc. etc.
