Macro roll default to 1 if zero or below?

Good evening all. I'm trying to update a macro for a custom system I've been running, and I can't quite seem to get the result I want. Here's the current iteration: &{template:default}{{name=HP DMG Resistance}}{{HP DMG after Resistance is [[(?{Damage|0}-(?{Resistance Reduced?|No,No|1d4,1d4|1d6,1d6|1d8,1d8|1d10,1d10|1d12,1d12|1d20,1d20}-@{Resistance})))]]}}{{NOTE: Resistance can only reduce HP DMG to 1.}} How would I go about adjusting it so that the roll result automatically shows a 1 whenever the math works out to be zero or a negative number?

What is in the @{Resistance} attribute? Just a number, or a text value, or a die roll? The basic idea would be something like this: [[{[[?{Damage|0}-?{Resistance Reduced?|No,0|1d4,1d4|1d6,1d6|1d8,1d8|1d10,1d10|1d12,1d12|1d20,1d20}-@{Resistance}]],1}k1]] But I'm not sure if that's going to give you the actual result you want.  If you give a little more information on how the mechanic works, then someone can likely give you a working inline roll macro.

Thank you!!! That works like a charm! Short summary: I'm using a heavily updated version of the Heroes of Remnant system (fan-made RWBY TTRPG system). After a character's protective energy ("Aura") is stripped away by damage, they're subject to attacks hitting their HP. Resistance is a type of damage mitigation stat based on the character's Toughness stat plus optional boosts from certain Skills -- it can reduce damage to 1, but not prevent it entirely. I've tested the code you set up and it seems to represent that perfectly! Thanks again!!
