You need to include which character sheet the ability roll is on, like: [fumble](~NAME|fumble] Change NAME to the relevant character sheet name, or selected. When a button is rolled from the character sheet, roll20 knows which
sheet it is coming from. When you click a button in chat, roll20 cannot
tell which character sheet's button you want to use, so the information
has to be included. I'm still waking up so I cant remember how to generate the character sheet name automatically, to send with the rolltemplate, but I'm sure someone else will or this might point you in the right direction.
