i am writing up a invoice program, when i add an invoice to the database " i go check its there" then i run the preview so it will show me the invoice info, it shows the right invoice no, but the data is blank, if i go on one of the old invoices i added before, it shows all the info, i have to close the whole prog and then come back in then i can see my newly added invoice in preview,, help pls

did you commit the transaction in which you added the data?
Maybe the record was added and comitted but the update setting the actual data wasn't yet comitted?
