selected = true

Hey all. Does anyone have any ideas how I can carry over a selected value? :) It's probably easy but my mind is making it difficult. A value is stored for a record in the DB which had been previously assigned through a select statement. If that record gets edited, the value that was chosen through the select does also, and that would necesitate another select statement, but for the ease of use, I would like the current value to be the selected one. The catch is, the values in the select statement come from the db because they depend on what the user inputs. Any ideas? Thanks Jason
