Horvald said: Matthew, this is a known factor of the sheet. I think basically that formulas like that [[ in double brackets]] are not evaluated until the roll, so they would not show up in the bonus listed on the sheet. Good news though, when I tested different ways to do this, I discovered you can mix/match attribute calls and math inside simple parentheses. It does show the math when you mouseover the roll, but it adds the bonus in the character sheet. So, your entry is truncated by the screenshot, but a generic version might look like this: +(@{attribute_1}*@{attribute_2})[testbonus] Hope that helps. I get the issue with the attack value not calculating in the list even if I provide a constant bonus using a label, e.g. +5[SpecialBonus] I am using the double brackets because otherwise the full formula is displayed in the roll card's tool tip. If I use double brackets and no label the attack is correctly calculated in the attack list. So far I haven't noticed it making a difference in any calculation whether I use them or not. Not being able to use a label in the attack bonus field isn't that big of a deal, since I am not currently concerned with bonus stacking. It's mainly useful for debugging the formulas I enter to see what calculations are adding which values. That is working in the roll cards. Here is the formula I am using to add the Mechanics's Combat Tracker bonus to an alternative attack entry (adding the difference between the class level and the class BAB, effectively following the BAB replacement rule): +[[@{class_1_level}-floor(@{class_1_level}*@{class_1_bab})]] (If there is a way to reference the fully calculated class BAB instead of doing the math that would be nice to know, but I don't see anything in the attribute list)
