Coal Powered Puppet said: So if I am getting this right... Strength, Agility and Toughness (for example) all receive bonuses based on if the person is in tager form or not. Those stats are calculated by value="@{Strength} + (@{tager_form_Strength_bonus} * @{form switch})". And the form switch is a radio button with a value of "0" (when set to human form) and to "1") when in tager form. Does that sounds right? Sorry, I was envisioning you wanting something different. 😀 If you just want to add some sort of bonus to multiple ability rolls if a toggle is switched or not, then what Mark is talking is correct. I think your example gets you there, but here's an example from my sheet: [[{1d@{Unskilled}![Unskilled], 1d@{wilddie}![Wild Die]}kh1 -2[Unskilled Penalty] + {0,@{JackOfAllTrades}}kh1 [Jack of All Trades Modifier] + @{ttmod}[Trait Test Modifier] +(@{UnskilledEncumbrance}*@{encumbrance})[Encumbrance Penalty] - @{woundsMod}[Wounds] - @{fatigue}[Fatigue]]] The bold bit is the relevant piece. Essentially, I have checkbox called attr_JackOfAllTrades with a value=2. Then if that field is checked it will add 2 to the roll, if it's not checked, it adds 0 to the roll. So you could do the same sort of thing and apply that field check to the different rolls. I hope this helps.
