Javascript - Function to move divs up and down.

I need a piece of Javascript code that can rearange a list of divs by clicking on a button. The ammount of itens are variable and they will be generated by a php code. The number of itens cant be on the function declaration but maybe on function paramters. Every div will need an original identifier (given non sequential based on his ID at mysql db and he actual order). I will need a form variable ( may be a hidden field ) with the new order of the divs. Check the file to see how the interface looks. This is a SMALL chuck of a HUGE project. If we like the coder and if hes avaliable we will be issuing like 100+ bids for similar small js scripts. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
