I just bought the Keeper Handbook for Call of Cthulhu and first I was a little frustrated that while the monster stats are listed on their 1st tab, I have to input values for the skills and combat options for each monster. Then I noticed that all combat I set up for the monster result in the following error message: SyntaxError: Expected "(", ".", "[", "abs(", "ceil(", "d", "floor(", "round(", "t", "{", [ |\t], [+|\-] or [0-9] but end of input found. So I can't seem to even just attach a custom combat button to a Fighting or Custom skill without getting that error. Even if I narrow down the damage rolls to no roll. The skill works on its page but the combat can't seem to roll even when associating, say Bite, to an established skill or a custom one.
