ChatSetAttr - Deducting from a repeating section

In one of my campaigns, the characters carry torches in their equipment section - which is a repeating section.  I've made it so they all have their torches as the first entry, but what's the best way to deduct 1 from their inventory when they use a torch.  I'm using Torch and TokenMod to change the character's light emitters, but I need a way to deduct one from their inventory.  This is my first time using ChatSetAttr, so please forgive me for what may sound like a dumb question. Thank you!

Hello, !setattr --silent --sel --class_resource|[[@{selected|class_resource} -1]] You can replace sel by the character name or target :) (Class_resource is the first repeating resource, the next one is other_resource... and I don't remember the next ones but you can find it with holding your mouse on the field I believe) :)

Thanks, but that didn't work - but it did give me an idea to try.  I'm using the 1st Ed AD&D character sheet in that particular campaign. With a mod to the command, I got it to work!  I had to go with: !setattr --silent --sel --repeating_equipment_$0_quantity|[[@{selected|repeating_equipment_$0_quantity} -1]] So I thank you very much for pointing me in the right direction!  :)

Sorry, I assumed you used 5e OGL :) Glad can help

No worries!  :) I guess I'm just (really) old school.  :D
