Global mod. Help. Using d&d 5e sheet

Here’s the description: When you make an attack while wielding more than one light melee weapon and make an attack with one of them, you can subtract the damage dice of another light melee weapon you are carrying from the attack roll to add twice its damage dice to the damage roll of that attack on hit. Using daggers. GAM:  ROLL:?{LS? |Yes,- d4|No,0}   GDM: DAMAGE:   ?{LS?|Yes,d4|No,0}*2 I’d like to be able to toll the GDM independently of one another. The GAM doesn’t seem to be working with a minus (works without, and i’m doing the math manually either way, just wanted to see if it was a possibility) Any help would be appreciated.

The problem you are probably having is that you cannot have the same query have two outputs. Move the "-" to before the GAM roll.  GAM: -?{LS?|Yes,d4|No,0} and  GDM: ?{LS?|Yes,d4|No,0}*2

GAM doesn’t seem to work. Will prompt correctly, but won’t spit out the attack roll even with the - outside .

Please screenshot the output.  Also, please copy the template it outputs.  You can do this by clicking on the Chat Tab's chat box (where you type), then hit the up arrow on your keyboard. That should be the template, copy that and paste it please.  Edit: you also have another problem in your GAM, you have a space in there that isn't in GDM.  You have to be careful with those spaces. 

Never mind, I figured out the problem, it really doesn't like a minus sign.  To make it work use this: ?{LS?|Yes,d4|No,0}*(-1)

That works. Appreciate the help :)
