Hey so I am making a custom character sheet for my Gamma World 2e (mutated rule set), and the issue I am having is that there is are mutations that have one bonus to Hit and a different bonus for Damage for physical attacks. My original thought process was to use 2 check boxes and have one hidden. So if you checked the one box the other would be checked automatically. So far I am able to make what I want to work in fiddle but cant make it work in roll20. So far I have this: JSFiddle This is going to be in a repeating section for the players attacks. Any other ideas to do what I require would also be welcomed. I will say I don't feel comfortable using API. So if the aid you give uses API I will need more help then using the HTML with <script type="text/worksheet">.
