Rolling formula's after the "<"

So here's my problem.&nbsp; this the formula I would like to use.&nbsp; /roll 1d100&lt;@{attributeA}+@{attributeB} &nbsp; I am playing a Black crusade game and trying to develope macros to roll skills.&nbsp; However, no matter how I set up the formula, the target number for successes is always attributeA with attributeB added to the total number of successes.&nbsp; Example would be if the formula looked like this, /roll 1d100&lt;34+10.&nbsp; On a roll of 34 or less the number of success would be 11.&nbsp; On a roll of&nbsp; 35 or more the number of successes would be 10. How can I fix it so that the computation of attributeA + attributeB happens before the number of successes are determined?

Unfortunately, we cannot do what you want directly. But we can play with the terms mathematically to do it. /roll {1d100-B}&lt;A is mathematically identical to: /roll 1d100&lt;(A+B) The macro you want is: /roll {1d100-@{attributeB}}&lt;@{attributeA} - Gauss

I need to check if Roll20 is capable of calculating negative numbers because the problem with that formula is, if it's not then I would not know easily how many degrees of success I had.&nbsp; Degrees of success are determined by each full ten you are lower than the target number.&nbsp; With that in mind though, is it possible there is a formula to calculate degrees of success?

From what I understood of your original post you wanted the successes to be either 1 or 0. The formula I provided does that.&nbsp; As for degrees of success, Roll20 is not set up to calculate that. You will need to do that manually. Sorry. :) - Gauss

Thats what I thought.&nbsp; :)&nbsp; TY.&nbsp;
