'Cough is not a valid member of folder'?

So me and my friends are making a virus-disease-based simulator, and I am debugging some code with print statements. I cant get passed the Debounce if statement because it claims that 'Cough is not a valid member of Folder'. Please help.

local replicatedStorage = game:GetService("ReplicatedStorage")
local remoteData = game:GetService("ServerStorage"):WaitForChild("RemoteData")

local cooldown = 1

replicatedStorage.Remotes.Cough.OnServerEvent:Connect(function(player)
	
	print ("Fired")
	
	if not remoteData:FindFirstChild(player.Name) then return "NoFolder" end
	
	
	
	local debounce = remoteData[player.Name].Debounce

	if not debounce.Value then
		
		print ("Got past the Debounce if statement")
		
		debounce.Value = true
		
		player.leaderstats.Cough.Value = player.leaderstats.Cough.Value + 25 * (player.leaderstats.Rebirths.Value + 1)
		
		wait(cooldown)
		
		debounce.Value = false
		
	end
	
end)

NOTE: The print statements are included for debugging. Just in case you were wondering.
