Module –

local Bar = {}

local Values = {}
function Bar:Add (humanoid,Number,TypeOfBar,Name)

		print(TypeOfBar)
		local att = humanoid:GetAttribute(TypeOfBar)
	humanoid:SetAttribute(TypeOfBar, att + Number)
	

table.insert(Values,TypeOfBar)
table.insert(Values,Name)
table.insert(Values,humanoid)
table.insert(Values,Number)

end

function Bar:GetValue ()
	return Values
end

return Bar`

Script: `

local Module = require(game.ReplicatedFirst.BarsModule)
script.Parent.Touched:Connect(function(h)

	if h.Parent:FindFirstChild("Humanoid") then
		
		local human = h.Parent:FindFirstChild("Humanoid")
		while wait() do
					Module:Add(human,10,"Oxygen",script.Parent.Name)
			if script.Parent.TouchEnded then
				break
			end
		end

	end
end)`

(This is a repost) so dont report for spamming

The error is pretty straightforward: you’re trying to add nil with some number. In this case, you only have one addition operation and the left-hand side of the addition is att, so we now know that att is nil. The attribute probably does not exist. If you ahve a default value for that attribute like 0 you can replace the line where you define att with:

local att = humanoid:GetAttribute(TypeOfBar) or 0
