Attempt to index nil with instance

Help and Feedback Scripting Support
#1

When I tested my game, and pressed the bind to activate combat, all that happened was: ServerScriptService.Stuff.StunningHandler:14: attempt to index nil with Instance
local Stunning = require(script:WaitForChild(“Stunning”))

local StunningHandler = {}

function StunningHandler.addTo(Player,Action)
Stunning[Action][Player] = true
end

function StunningHandler.removeFrom(Player,Action)
Stunning[Action][Player] = nil
end

function StunningHandler.findPlayer(Player,Action)
return Stunning[Action][Player]
end

return StunningHandler

#2 
local sus = {}
local b = sus == {} -- it's a boolean

print(sus.amogus) --> nil
print(b.amogus) --> attempt index boolean with amogus

Greetings RoboL1nk,

It seems to be an error to do with you trying to access an “item” in a module script which doesn’t exist. If you are trying to access an item in a table, I suggest debugging it first with a simple print.

local Stunning = require(script:WaitForChild(“Stunning”))

local StunningHandler = {}

function StunningHandler.addTo(Player,Action)
    print(Stunning[Action])
    print(Stunning[Action][Player])
    Stunning[Action][Player] = true
end

function StunningHandler.removeFrom(Player,Action)
    print(Stunning[Action])
    print(Stunning[Action][Player])
    Stunning[Action][Player] = nil
end

function StunningHandler.findPlayer(Player,Action)
    print(Stunning[Action])
    print(Stunning[Action][Player])
    return Stunning[Action][Player]
end

return StunningHandler

If the first print fails that means “Stunning” doesn’t exist. From there you can take more actions to fix this.

Was able to Combine this print and another one mamytema sent and I was able to figure out the mistake. Thank you so much.
