[Macro Help] How do you set a minimum damage value?

I have a pseudodragon as a cohort. There's a lot of different thing's in this macro all of which work.  It's attack is 1d3-2 plus any damage from the skirmish ability which is in the macro as a toggle on/off. However I need to set the minimum damage to not be lower than 1. Even with the skirmish ability, I could roll a 1 on the d3, a 1 on the d6 and end up with a total of 0 damage. Obviously on a roll like this minimum damage would be 1, but that's not what the macro show's. Here is the Macro. &{template:DnD35Attack} {{pcflag=true}} {{name=Tanis}} {{subtags=uses poision sting!}} {{attack1=A1:[[d20cs+10+?{Attack|0}]]}} {{critconfirm1=Crit?:[[d20+10+?{Attack|0}]]}} {{damage1=D1:[[1d3+?{Damage|0}+?{Skirmish?| No, [[0]] |Yes,[[1d6]] }-2]]}} {{critdmg1=+[[(d3-2+?{Damage|0})]]}} {{fullattackflag=[[?{Draconic Zeal|0}d1]]}} {{attack2=A2:[[d20cs+10+?{Attack|0}]]}} {{critconfirm2=Crit?:[[d20+10+?{Attack|0}]]}} {{damage2=D2:[[1d3+?{Damage|0}-2]]}} {{critdmg2=+[[(d3-2+?{Damage|0})]]}} {{attack3=A3:[[d20cs+10+?{Attack|0}]]}} {{critconfirm3=Crit?:[[d20+10+?{Attack|0}]]}} {{damage3=D3:[[1d3-2+?{Damage|0}]]}} {{critdmg3=+[[(d3-2+?{Damage|0})]]}} The minimum value would need to also be set for attack 2 and 3 as well as all critical damage. Any help would be appreciated.

{2 , [[your normal damage roll]] }kh1

I will give it a shot and try it out. Was messing with KH1 but not in that way.

{{damage1=D1:[[{1,[[1d3+?{Damage|0}+?{Skirmish?| No, [[0]] |Yes,[[1d6]] }-2]]}kh1]]}} This line seems to work as intended while testing it. I'm either getting 1, 2, or 4 so far out of 6 rolls. Will keep trying. 7 is the highest damage possible. That seems to work just fine. After about 10 rolls, got a 7 and several threes. Just need to edit the rest of the macro in the same way. Thank you!
