Visual Basic help continued

For the problem that I listed a couple hours ago, I'm also supposed to create another command button, that when pressed, takes the items from the second list box, and moves them up one position in the list (i.e. second item in the list gets moved and becomes the first item on the list when i push the command button). It's supposed to work even if I select more than one item to move, and if the item that i attempt to move is the first one in the list, it should not move. I know that I have to use a temporary variable, but I am having trouble figuring it out. If anybody has any idea, their help would definitely be appreciated. Thanks.
