how do I fix roblox sword damage not updating?

I made a sword that changes damage based on a value called pwr. You can increase the value by killing a npc. But when it increases it only increases once even though the value changes. I found out if I changed the value before starting the game then the damage is the same as the value but it wont increase even when the value is increasing.

this is the part of the script I used for custom sword damage.

DamageValues = { BaseDamage = 1, SlashDamage = script.Parent.pwr.Value, LungeDamage = script.Parent.pwr.Value * 2 }

this is the whole script

Tool = script.Parent Handle = Tool:WaitForChild("Handle") local dam = script.Parent.pwr

function Create(ty) return function(data) local obj = Instance.new(ty) for k, v in pairs(data) do if type(k) == 'number' then v.Parent = obj else obj[k] = v end end return obj end end

local BaseUrl = "rbxassetid://"

Players = game:GetService("Players") Debris = game:GetService("Debris") RunService = game:GetService("RunService")

DamageValues = { BaseDamage = 1, SlashDamage = script.Parent.pwr.Value, LungeDamage = script.Parent.pwr.Value * 2 }

		local Anim = Tool:FindFirstChild("R15Slash")

You need to update the damage every time it changes, right now it only updates one time.

Something like this. (this script probably wont work cos i dum 0:)

DamageValues = { BaseDamage = 1, SlashDamage = script.Parent.pwr.Value, LungeDamage = script.Parent.pwr.Value * 2 }

script.Parent.pwr:GetPropertyChangedSignal'Value':Connect(function()
	DamageValues.BaseDamage = 1
	DamageValues.SlashDamage = script.Parent.pwr.Value
	DamageValues.LungeDamage = script.Parent.pwr.Value * 2
end)

What if you did

local BaseDamage
local SlashDamage
local LungeDamage

game:GetService'RunService'.Heartbeat:Connect(function()
	BaseDamage = 1
	SlashDamage = script.Parent.pwr.Value or 1
	LungeDamage = script.Parent.pwr.Value * 2 or 1
end)

--[[
also edit rest of script so theres no 'DamageValues' before basedamage, slash, and lunge
