GiGs said: The are two different methods of automating chat rolls: Macros, and Abilities. Abilities are on a character sheet, in the Attributes and Abilities tab. You should be able to make your macro work from there with /roll 1d20+@{pb}+@{dexterity_mod} Macros are different. They are in the right sidebar of roll20, and since they aren't connected to a character, you have to supply a character name for them to work. If your character is called Frodo, you would do this /roll 1d20+@{Frodo|pb}+@{Frodo|dexterity_mod} you can also use selected in place of a character name, and then if you have a token selected it will use the character's stats linked to that token. /roll 1d20+@{selected|pb}+@{selected|dexterity_mod} Does this solve your problem or do you still need help? I think if these aren't working, there's something wrong with your attributes. You need to check they contain numbers. This works beautifully, I thought if i had a token selected and tried to call @{pb} it would work, but including the specific character in the macro makes so much more sense.Thank you so much!
