So there are no modifiers? Nothing else being added to the d20? For future reference, it is generally a good idea to assume people don't know anything about the game you are trying to build a macro for. Treat them like you would someone playing for the first time. "First you roll a d20, then you add X, then divide by Y, multiply by Z, dance around, stand on your head, and then finally you get your answer" (semi-humor) Everything from start to finish factors into the answer that people can give you about a Macro. If something is added, substracted, multiplied, divided, rounded up, or rounded down it will affect the answer people can give you. It isn't just the d20 that matters. :)
