I would recommend posting a request in the stickied requests thread . Giving details about the system and possibly a way for people to see the existing sheet setup will help greatly but be aware that the kind folks with the knowing of the h, t, m and l's do this out of love and in their own free time so it may not be a quick resolution. I would HIGHLY recommend looking around the net to find html tutorials and trying your hand at a basic sheet yourself (that's what I did). Dissecting the work of others by getting the html/css from the Roll20 GitHub repository is a great way to advance your learning too should you feel up to the task.
