(HELP PLEASE) How to make my scripts giving +1 stage only for player who touched portal?

Explaination: Ok so i made a portals and scripts what teleporting player to next stage and giving to player leaderstats +1 stage completed. So, we have tested that system with my friend, and figured that script gives +1 stage completed to all players on server. So im wanna change it to make give +1 stage only for those players, who touched portal script.

Scripts:

Local StarterPack scripts(they are almost same, just part what player touching changed):

local touchName = "Stages"
	local rs = game:GetService("ReplicatedStorage")
	 
	local touchEvent = rs:WaitForChild('TouchEvent')
	local portal = workspace.FirstStage.FrostPartal.PortalPart
	local Debounce = false
	 
	portal.Touched:Connect(function()
		    if(Debounce == false) then
			        Debounce = true 
			        touchEvent:FireServer() 
			        wait(1) 
			        Debounce = false
end)

Server Leaderstats Script:

local function onPlayerJoin(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	
	local start = Instance.new("IntValue")
	start.Name = "Stages"
	start.Value = 0
	start.Parent = leaderstats
end

game.Players.PlayerAdded:Connect(onPlayerJoin)

local touchName = "Stages"
local rs = game:GetService("ReplicatedStorage")

local touchEvent = rs:WaitForChild('TouchEvent')



touchEvent.OnServerEvent:Connect(function(plr)

	plr.leaderstats[touchName].Value = plr.leaderstats[touchName].Value +1
	
	wait(1)
	
	
	

end)

First of all, why put the local script in starterpack scripts instead of in the workspace? Make a script in the workspace and parent it to the portal and insert this script here:

local DB = false

script.Parent.Touched:Connect(function()
if DB == false then
DB = true
game.ReplicatedStorage.touchEvent:FireServer()
wait(1)
DB = false
end

end)

After that, insert a script into ServerScriptService and input this code here:

game.ReplicatedStorage.touchEvent.OnServerEvent:Connect(function(plr)
plr.leaderstats.Stages = plr.leaderstats.Stages + 1

end)
