Function won't detect NumberValue change?

I have been working on a fighting game where you can send out a blast forward from your hands. When you press Z, a large blast is fired and a hitbox is cloned and put in to the local character's model. After that, the script inside the hitbox that was cloned is re enabled and this simple script runs. Afterwards, the script is destroyed and then you can fire the blast again after the cooldown.

All worked well up until I tried making a value that you can change to determine how much damage your blast did to another player. For every player that spawns in, they get their own folder in replicated storage which stores their variables, etc. Strength is one of those variables.

The problem I'm having is the script works fine, but when I attempt to change Strength's numbervalue the previous value is still being loaded, even though the referencing should be fine. Please help!

local char = script.Parent.Parent
local playername = script.Parent.Parent.Name
local folder = game:GetService("ReplicatedStorage"):WaitForChild(playername)
hasbeenhit = false

script.Parent.Touched:Connect(function(touched)
if touched.Parent ~= nil and touched.Parent:FindFirstChild("Humanoid") and hasbeenhit== false then
    if touched.Parent ~= char and touched ~= char then
    touched.Parent.Humanoid:TakeDamage(10 + folder.Vars.Strength.Value/2)
                hasbeenhit = true
            else    
                --do nothing            
            end
    end
hasbeenhit = false
end)
