local module = {}

function module.AddEffect(char,effect)
	local character = char
	local effects = character:WaitForChild("Effects")
	local search = effects:GetDescendants()
	for i,v in pairs(search) do

function module.RemoveEffect(char,effect)
	local character = char
	local effects = character:WaitForChild("Effects")
	local search = effects:GetDescendants()

return module

This script keeps returning a ReplicatedStorage.EffectManager:8: attempt to index nil with ‘WaitForChild’ error, which doesn’t seem to be doing anything but is incredibly annoying. Can someone tell me why?

#2

does the character exist, and does effects exist

#3

Yes. Yes they do.

Character is literally defined in the function params.

#4

No,u are wrong.those are the send parameters

If u want to prove to me that they exsists,

Print(char) and print(effects)

And show me that effects and i think characater == nil

#5

its not in serverstorage its in the character itself…

And yes, they did print.
