I want to create roll buttons which take into account attributes. I used many syntax but I cannot achieve this. As far as I understood the documentation, it should be simple. I tried syntax like: ${id_dext}+3d6p[1:blue] or ${dext}+3d6p[1:blue] but in Rolisteam the syntax is not understood. By the way ${dext} or 3d6p[1:blue] are OK. Have I misundertood the syntax or is it a real bug?

I have attached the character sheet file (without the background image): dragon-de-poche-bug.rcs
