Not all characters will have all attributes. Using @{selected|AttributeName} produces an ugly orange error message in the roller's chat window if the token doesn't have that attribute. In D&D or FATE, rolling a skill you don't actually have is a perfectly normal occurrence. While I could certainly add a script to give all characters a default 0 value for all attributes in the game upon creation, that can clutter the sheet up a bit, especially for games with lots of attributes. So, simple solution: @{<character>|<attribute>|<default>}, e.g., @{selected|Acrobatics|0}
