My sheet uses some hidden fields and dropdown menues to simplify the process of keeping track the leveling process. Not that it particullarly difficult, but it does aid in altering npcs on the fly. However, it has created some issues with converting my sheets fully to SheetWorkers. I was wondering if there was any way to cheat, fake or otherwise trick the SheetWorkers into accepting auto-calcs and other similar things. I know that the Pathfinder Sheet has some interaction between autocalcs and sheet workers for the HP Formula and skill ranks formula, so I know something like what I want is possible. At the very least having the SheetWorker match the string in the field and shove the correct formula in its place. The racial has drop-down selections for BAB and Saves, which I could easily convert into SheetWorkers, but the class choices have a regular field which uses hidden fields with formula for each. I do this because I want to allow players to enter the number manually, and I want to be able to use this auto-calc to create NPCs that I can increase in level on the fly. I am fairly certain I know a few ways to get a similar effect, the problem is the 300+ character sheets that use the above method. I can't really think of any way convert the BAB and Saves to SheetWorkers without causing a massive headache and telling people I need like a month off to convert all sheets to the new system. Any assistance in this would be appreciated.
