Sneak Attack macro and Multiclassing

I have a Rogue who just took one level of Fighter, and up til now has been using a very nice macro to automatically calculate my Sneak Attack damage...now I'm not sure how to separate out the two classes for purposes of the macro: {1d8+[[ ceil((@{base_level}) / 2) ]]d6 [Sneak Attack]} I assume there must be a way to have the macro only use the Rogue levels in its calculation, but I'm not sure what the terminology is to replace "base_level". What should I use there?

"base_level" contains the number of levels of your initial class. "level" is your total levels. Assuming you started with Rogue, as you indicate, your formula should still be good.

Oh, cool beans! Thanks again!
