Removing Dice from Dice pool

So, I'm planning on running  a New World of Darkness game, and I've been creating my own macros. I'm having an issue with getting certain dice rolls to work properly. What I'm trying to do is something like this: [[(@{selected|Dexterity}+@{selected|Firearms})d10>8!+?{Situational modifiers}d10>8!+?{Weapon Damage}d10>8!]]. So that rolls their attribute plus their skill plus or minus Situational mods plus or minus the weapons damage. Is there a way that if the modifiers end up being a minus that it will remove dice from their overall dice pool instead of adding in negative dice?

[[(@{selected|Dexterity}+@{selected|Firearms}+?{Situational modifiers})d10>8!+?{Weapon Damage}d10>8!]] This would do it I think?

You're amazing. It was as simple as just moving the '( )' to wrap around the entirety of the roll macro instead of just those two. Thank you, that fixed it. Just needed fresh eyes to help me fix it.
