customization of ajax drag and drop folder tree

I need some modifications to the folder tree here? <[login to view URL]>.? namely: - to adjust some of its methods/properties -? to retreive the "countries" from and save changes to mysql tables - to calculate some items based on existing mysql data and the groupings provided by the treeview and insert them in a mysql table? - some script and assistance are also necessary to integrate this facility smoothly into my website. ## Deliverables full specs are attached.
