    Hi!We are some students at Oslo University College who got this assignment to make a JavaScript that switch the contents in a dropdown list. The highlighted word in the left dropdown list is supposed to copy into the right whitout disappearing from the left, than move down to the bottomn of the left list. The secound word transferred to the right dropdown list is supposed to appear on top of the list. Hope you got this...take a look: http://members.lycos.co.uk/rlarsen/meny.html
