Hexblade Curse

Hello, I'm trying to make an all in one macro on the OGL 5e sheet for my pact weapon attack. Is it possible for it to query Hexblade Curse on the attack roll and damage roll and if yes change crit to 19+ and damage to add proficiency bonus. I can't see to find a way for it to pull the proficiency bonus into the damage line, or where to put the query for the crit modifier. Any assistance would be appreciated, I'm new to these, but greatly enjoy the feature. Additional question: Can I stack hexblade curse, hex, and Bestow curse?

I'm pretty sure the attribute you need to call for Proficiency Bonus on the 5e OGL sheet is "pb".  For the added crit range the syntax is along the lines of "1d20cs>19" Is your second question a D&D rules question or a Roll20 question?  If rules, then no, because hex and bestow curse are both concentration spells.

Doesn't seem to work, When I try to query for damage and confirm if hexblade is active or not, I want it to add pb damage to the roll and if not don't add it to the roll. I also want the query to modify the cs to 19, but I just seem to not be able to figure out how to combine it all. Yes, it was a rules question, but can I have hexblade curse + hex or bestow curse?

Maybe post the macro you're working with then we can error check it? (yes you can stack the curse with hex or bestow curse)

This is what I've been trying Query if the curse is active if yes add proficiency bonus if not nothing then roll for damage. [[?{Hexblade Curse?|Yes,PB|No,0}+1d10]]

Think you need to precede the "PB" with an attribute call  to refer to the character who's PB you are using. ie. @{selected|PB} or @{Character's Name|PB}

[[?{Hexblade Curse?|Yes,@{Character's Name|PB}|No,0}+1d10]]?

No, that actual name of the character; not "Character's Name". :P ((hoping someone that actually knows what they're doing comes into this thread and saves us from fumbling around trying to figure it out together.))

Haha yeah, i just put it as a place holder it would be [[?{Hexblade Curse?|Yes,@{Va'Naan Shadowblade|PB}|No,0}+1d10]] is what i tried and it didn't work, I mean I'm being a little of a try hard I could just make a 2nd attack that does all this manually, lol
