checke om findes i record ellers ikke tilføje
Det her bliver nok lidt bøvlet at forklare.Hvordan kan man tjekke at {rs.vaerdi} ikke bliver tilføjet hvis den alledere i recordsættet rs.liste?
kan man tilføje det må en smart måde evt. med et javascript alert hvis den allede er tilføjet?
Evt. noget i retning af denne SQL:
"SELECT * FROM hent_preferencer WHERE CID is not (listen på formen) AND produkt_id = " + osv.
HER ER KODEN:
