Javascript Changes

Have some existing javascript that works really well but needs to be altered slightly as I have made one or two changes to the web pages using this script. Should be a quick job....could probably do it myself given the time (always in short supply). The script is all there so there is probably no need for any new additional script. There is also a problem with DHTML coding which is working on other similar pages but not the new ones I am creating so some help there also is required
