select menu's

Hey here is my delimma i have 2 select menu's side by side the one on the left pulls the current information of the doctor and the one on the right has all the possible selections of departments and locations to add to a doctor. Right now they are a simple javascript that moves them from one to the other but thats all. I want to have it where when the user moves one item over it will post back and automatically go to the databse and add the information or delete the information depenting on what the user is doing. This is a VBScript page witha little javascript in it any help would be greatly appreciated :sick:
