why value is still the same, when i do value * value please help me?

script.Parent.Events.DamageEvent.OnServerEvent:Connect(function(plr)
local damage = script.Parent.Damage --//Damage = 0 
local starterdamage = script.Parent.StarterDamage --//Damage = 4
local Level = game.ReplicatedStorage[plr.Name.."Data"].Level 
local Damagecandeal = game.ReplicatedStorage[plr.Name.."Data"].DamageCanDealByFruit --//Damagecandeal = 0
local Stats = game.ReplicatedStorage[plr.Name.."Data"].Stats --//Stats = 3 

while true do
	 wait(.1)
	 Damagecandeal.Value = starterdamage.Value * Stats.Value
	 damage.Value = Damagecandeal.Value
	 print(damage.Value)
         --//0 / the print
end
end)

it prints(0) ?

Oh my god. Please learn some basic naming convention for Lua before scripting. This code is unbearable. Spacing is random, variable names' case is random, comments are basically nonexistent (apart from those that you put to indicate what the values should be). Please read this. It'll help.

For your question. Are you sure your values are set? Are you sure starterdamage.Value is 4 and Stats is 3?
