Remote Event seeming not to work correctly?

I'm trying to make it so when you click a button, it resets your stage and resets your datastore. I'm a beginner to remote events, so this is probably an easy fix.

Here is my code:

--code in the localscript

local data = game:GetService("DataStoreService"):GetDataStore("Stage")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local resetDataEvent = ReplicatedStorage:WaitForChild("ResetDataEvent")
 

script.Parent.MouseButton1Up:connect(function()
	game.ReplicatedStorage.ResetDataEvent:FireServer()
end)




--code in script

local function resetData(plr)
	print("hi")
	plr.leaderstats.Stage.Value = 0
	local key = "user_" .. game.Players.Localplayer.userId
	data:SetAsync(key, game.Players.Localplayer.leaderstats.Stage.Value)
end

game.ReplicatedStorage.ResetDataEvent.OnServerEvent:connect(resetData)

This code is basically ripped off the wiki. Please help!
