Regards to all, I have a problem, is a window with several fields (you can see the image) when I select a shipper, I have to bring your address from the table, yet do another query to fetch the starting points that have the sender, these are multiple rows and these will fill a combo (would be a store). Similarly following combos work. I wonder how I can implement this. How do I run those 2 queries. My apologies for my bad English.
