Keeping entries of a select-box after submitting the form

Hi everyone, Well, I have already formulated my problem several times, always in a different way, but yet I have no solution. I try to say it as easy as it gets: I simply want one specific selction-box to 'keep' ALL options present after having submited the form! I'm thinking about a variable or something that contains all that options, and not just only ONE like the value-variable. I hope this is clear now. Regards, André
