Can someone help me figure out how to change leaderstats in a separate script?

I am having trouble trying to figure out how to change leaderstats in a separate script. I want it to work so that when a player is touching the part it will give them 1 EXP every second, and this is in a local script. Here is the script

local Player = game.Players.LocalPlayer

local LeaderStats = Player:WaitForChild("leaderstats")

local Level = LeaderStats:WaitForChild("Level")

local EXP = Player:WaitForChild("EXP")

script.Parent.Touched:connect(function(touch)

if touch.Parent:findFirstChild("Humanoid") then

touching = true

while touching do

EXP.Value = EXP.Value + 1

wait(1)

end

end

end)

script.Parent.TouchEnded:connect(function(untouch)

if untouch.Parent:findFirstChild("Humanoid") then

touching = false

end

end)

Normal Script

local t = false
script.Parent.Touched:Connect(function(touch)
	if touch.Parent:FindFirstChild("Humanoid") and t == false then
		t = true
		local plr = game.Players:FindFirstChild(touch.Parent.Parent.Name)
		plr:FindFirstChild("leaderstats").EXP.Value = EXP.Value + 1
	end
end)

script.Parent.TouchEnded:Connect(function(untouch)
	if untouch.Parent:FindFirstChild("Humanoid") and t == true then
		t = false
	end
end)
