How do I make a stat increasing tool?

removing holdername = nil might work and make it holdername. Otherwise, you can try this:

Step 1: Make a RemoteEvent called 'Give' and put it in ReplicatedStorage. Step 2: Make a script and name it 'Function' and place it in ServerScriptService. Here's the code for that:

local remote = game.ReplicatedStorage.Give

remote.OnServerEvent:Connect(function(Player)
	local plr = Player
	plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value + 1
end)

Step 3: Clearly the leaderboard in ServerScriptService:

game.Players.PlayerAdded:connect(function(p)
	local stats = Instance.new("IntValue")
	stats.Name = "leaderstats"
	stats.Parent = p
	
	local money = Instance.new("IntValue")
	money.Name = "Cash"
	money.Value = 0
	money.Parent = stats
end)

Step 4: Now create a screengui in StarterGui and name it 'popUp' Step 5: Then insert a 'TextLabel' (You can use a ImageLabel but u will have to change the code in the tool later on) into the popUp and set these properties:

• Visible: False
• TextScaled: True
• BackgroundTransparency = 1
• and any other settings should be okay, expect TextTransparency.

Step 6: Now name the text label 'ImageLabel' If you decided to use a ImageLabel instead, this step isn't needed.

Step 7: Create a tool with a handle.

Create a tool and name it 'Cash Giver' or whatever you please. then place a part inside it and name it handle, customize that handle, then place the tool in StarterPack.

Step 8: Add scripts and tool settings

Make sure the tool has these settings:

• RequiresHandle: True
• CanBeDropped: False
• Enabled: True
• ManualActivation: False
• Archivable: True

Now let's make the scripts:

Script 1: add a local script and name it 'Detector' then insert this code into it:

script.Parent.Unequipped:Connect(function()
	script.Parent.LocalScript.Disabled = true
end)

script.Parent.Equipped:Connect(function()
	script.Parent.LocalScript.Disabled = false
end)

Script 2: add a local script and do not name it, then insert this code into it:

local remote = game.ReplicatedStorage.Give

script.Parent.Equipped:Connect(function()
	if script.Parent.Equipped then
				game.Players.LocalPlayer:GetMouse().Button1Down:Connect(function()
				local plr = game.Players.LocalPlayer
				plr.PlayerGui.popUp.ImageLabel.Position = UDim2.new(0, plr:GetMouse().X, 0, plr:GetMouse().Y)
        		plr.PlayerGui.popUp.ImageLabel.Visible = true
				script.Disabled = true
				remote:FireServer()
        		for i = 1, 10 do
            		wait()
            		plr.PlayerGui.popUp.ImageLabel.TextTransparency = plr.PlayerGui.popUp.ImageLabel.TextTransparency - 0.1
        		end
        		wait(0.5)
        		for i = 1, 10 do
            		wait()
           		 plr.PlayerGui.popUp.ImageLabel.TextTransparency = plr.PlayerGui.popUp.ImageLabel.TextTransparency + 0.1
				end
				plr.PlayerGui.popUp.ImageLabel.Visible = false
				script.Disabled = false
			end)
		end
	end)

If you plan on using a ImageLabel instead, it's very simple to change:

-- Old:
plr.PlayerGui.popUp.ImageLabel.TextTransparency = plr.PlayerGui.popUp.ImageLabel.TextTransparency - 0.1
-- New:
plr.PlayerGui.popUp.ImageLabel.ImageTransparency = 	plr.PlayerGui.popUp.ImageLabel.ImageTransparency - 0.1	
-- and clearly change where the + is instead of the -, change the wording to ImageTransparency.

Please accept if this worked! Also please give credit.
