Hello, I am attempting to recreate the double cross 3rd edition character sheet in the roll 20 custom sheet creator. I am basically inept at html but I wanted to be able to make the sheet to where all the math is done behind the scenes so everyone playing doesn't have to spend a lot of time working out numbers and we can jump right in, the issue is that the classes have base stats but you can pickup to 3 classes and the numbers are effected by what you pick, if only one class is chosen the base stats are doubled, if you pick 2 or 3 classes the values of the first 2 classes are added together. I need to be able to have the dropdown list have not only the names of the classes but also the values assigned to them and based on the number of classes picked add or multiply the stats. is this at all possible with html?
