Solved how to allow players to break/ place specific blocks?

i'm running a server where all players CANNOT break or place blocks such as dirt or stone, but CAN break/ place signs. ive tried literally everything to figure this out and i just cannot. heres what the rank "gray" ive been using as a test has for permissions related to this problem. (i am using worldguard, essentials, and groupmanager)

Code:

Gray:
    default: false
    permissions:
    - essentials.build.break.63
    - essentials.build.break.acacia_sign
    - essentials.build.break.birch_sign
    - essentials.build.break.dark_oak_sign
    - essentials.build.break.oak_sign
    - essentials.build.breal.spruce_sign
    - essentials.build.place.63
    - essentials.build.place.acacia_sign
    - essentials.build.place.birch_sign
    - essentials.build.place.dark_oak_sign
    - essentials.build.place.oak_sign
    - essentials.build.place.spruce_sign
    - essentials.build.use.63
    - essentials.interact.*
    - essentials.protect.exemptbreak
    - essentials.protect.exemptplacement
    - essentials.protect.exemptusage
    - essentials.signs.use.free
    - worldguard.build.block.interact.oak_sign
    - worldguard.build.block.place.oak_sign
    - worldguard.build.block.remove.oak_sign
    - worldguard.build.item.use.oak_sign
inheritance: []
    info:
      build: false

also any time they try to place a sign it said "You are not permitted to use OAK_SIGN."

 

In GroupManager, there is a feature known as negative nodes. You can add build permission (which includes place, break, interact) and remove permission to break dirt / stone using negative nodes

 

i figured it out after using /ess debug and... using my brain a bit.
these are the commands used to allow breaking, placing, interacting, and picking up of EVERY SIGN TYPE.
keep in mind that if you want the player to be able to place them, you need to have the permission "essentials.build.interact.*"

Code:
