My rank is one of the required ranks in the group, but the remote event is still not firing?

atease.MouseButton1Down:Connect(function()
	if debounce == true then
		for i = 1,#ranks do
			if rank == i then
				
				-- Same thing as written above, already made it rank-locked for you.
				rease:FireServer()
			end
		end
	else
			return
	end
end)

That is the function, and the following is the associated variables:

-- Miscellaneous References

local debounce = false
local replicatedstorage = game:GetService("ReplicatedStorage")
local player = game.Players.LocalPlayer

-- Reference Group Ranks

local ranks = {"Regulation Enforcement", "Adroit Enforcer", "Proficient Enforcer",  "Auror Division", "Meister Auror", "Veteran Auror", "Magical Architects", "Division Foreman", "Professor"}
local rank = player:GetRoleInGroup(3736685)
print(rank)
-- Remote Events

local rbow = replicatedstorage:WaitForChild("MobileBow")
local rease = replicatedstorage:WaitForChild("MobileEase")

I believe that the problem is

local debounce = false

if debounce == true then 
end
--it will never fun because you are basically doing this
if false == true then

end
--false == true is falsey

A debounce should work like this:

local debounce = false

atease.MouseButton1Down:Connect(function()
	if not debounce then
		debounce = true
		spawn(function()
			wait(1) --cooldown time for the debounce
			debounce = false
		end)

		--rest of the code
	end
end

Well the thing is that you didn't get the player in the code. Find some way to get the player and write in the code or else the script won't recognise what is

for i = 1, #ranks do

for...Also when you :FireServer(), player is automatically passed as argument so if you didn't get the LocalPlayer the script will not work...
