Hello All, I have been working on creating a custom character sheet for a game system I am trying to setup in Roll20. I have been looking through quite a bit of the guts for some of the more advanced character sheets, trying to figure out how they are auto calculating a value for the textbox from the values of several other entries. To date, I have not been able to find the exact path they are following to make it perform the calculation once all the fields have values. I have looked the most at the most recent version of the Pathfinder sheet and I have found all the fields, but I am not seeing how the actual calculation is performed so I can recreate it on my own sheet. Any suggestions?
