How to success/failure on number minus a selected attribute level?

Hello everyone! I have the following formula and still can't get my head around how to get a simple "Success" or "Failure" from this. The formula should check if a 2d6 roll is higher than the value 10 minus the level of an attribute: /roll 2d6>{10-?{What attribute to use?|Attribute1,@{Attribute1}|Attribute2,@{Attribute2}}} I guess, the trick is how to bracket in the 10 - attribute. with the {} brackets, I just get "2". Without the brackets, I always get "-4 Successes". With the [] or () brackets, it does not work as well. What would be the right way to check this? To understand the formula: if an attribute is leveled up to 4, it should calculate 10-4=6, so you need to roll a 6 with 2d6s. If your level is just 2, 10-2=8, so its harder because you need to roll an 8. Could anyone help? Greetings, Rastatux

It's better for this to use inline roll brackets [[ ]]. This forces an immediate calculation. /roll 2d6>[[10-?{What attribute to use?|Attribute1,@{Attribute1}|Attribute2,@{Attribute2}}]] You might find it more natural to switch things around: /roll [[2d6+?{What attribute to use?|Attribute1,@{Attribute1}|Attribute2,@{Attribute2}}]]>10 But your method does display the dice roll if you need to see that.

Oh yeah, thanks! I thought I could force the calculation within brackets or curly brackets... It works for "1 success"... However when the rolled dices are less than needed, it shows "0 Successes"... is it possible to change that to "Failure" or so?

Unfortunately no, that is a limitation of roll20's dice system. 

Ah okay... Still thanks, it works :)
