Du kunne når du poster gemme checkbox værdien i en session, og så tjekke den værdi når siden skrives på ny, kan du følge mig?

Ja, ja! Det lyder jo ikke helt dumt, det han taler om, men desværre har jeg prøvet noget lignende op til flere gange nu, men uden resultat.

Er der ikke nogen, der kan lave sådan en kode ud af min?

100 point... ;-)

Jeg skal nok kigge på det i aften, hvis jeg har tid! :o)

Jeg tror bare, at jeg selv finder ud af det.

Lukker!

Sorry, glemte dig helt!
