Level value in script isn't updating when the actual value updates?

Okay, so I recently started learning remote events and all, and I'm still quite new to them, but anyway, in my script, whenever I try to access the level of my character, it always thinks it's 0.

Server Script:

local repStorage = game:GetService("ReplicatedStorage")
local remoteEvent = repStorage:WaitForChild("LimitBreaker")

local multiplier = 2
local requirement = 1

remoteEvent.OnServerEvent:connect(function(player,enabled)
    local localScript = game.Workspace[player.Name]:WaitForChild("Skills"):WaitForChild("LocalLimitBreaker")
    local aura = localScript:WaitForChild("Aura")

    local level = player.leaderstats.Level

    local char = game.Workspace[player.Name]
    repeat wait() until level.Value ~= 0

    if enabled == false and level.Value >= requirement then -- The level variable doesn't change when the value does, and it thinks the level is 0, so this if statement never occurs.
        for i,v in pairs(char:GetChildren()) do
            if v.Name ~= "Humanoid" then
                for i,z in pairs(aura:GetChildren()) do
                    z:Clone().Parent = v
                end
            end
        end

        local stats = player.Stats
        strength = stats:WaitForChild("Strength").StrengthLevel
        speed = stats:WaitForChild("Agility").AgilityLevel
        jump = stats:WaitForChild("Jump").JumpLevel

        strength.Value = strength.Value * multiplier
        speed.Value = speed.Value * multiplier
        jump.Value = jump.Value * multiplier

    elseif enabled == true and player.leaderstats.Level.Value >= requirement then
        for i,v in pairs(char:GetChildren()) do
            if v.Name ~= "Humanoid" then
                for i,z in pairs(v:GetChildren()) do
                    if z.Name == "ParticleEmitter" then
                        z:Destroy()
                    end
                end
            end
        end

        strength.Value = strength.Value / multiplier
        speed.Value = speed.Value / multiplier
        jump.Value = jump.Value / multiplier

    end
end)

Client Script:

local repStorage = game:GetService("ReplicatedStorage")
local remoteEvent = repStorage:WaitForChild("LimitBreaker")

local UIS = game:GetService("UserInputService")
local enableKey = Enum.KeyCode.Q

local enabled = false
local db = false

local player = game.Players.LocalPlayer

UIS.InputBegan:connect(function(input)
    if input.KeyCode == enableKey then
        print("Key Pressed.")

        if enabled == false and db == false then
            db = true
            print("Enabled is false.")
            remoteEvent:FireServer(false)
            wait(1)
            enabled = true
            db = false
        elseif enabled == true and db == false then
            db = true
            print("Enabled is true.")
            remoteEvent:FireServer(true)
            wait(1)
            enabled = false
            db = false
        end
    end
end)

My level right when the game loads up is indeed 0, but it then changes to 1 and it doesn't update it in the script. Does anyone know an alternate way I can do it to where it actually works? Because I need this to have a certain level requirement for my game.

Note: It probably does the same with the strength, speed, and jump variables and puts them in as what they are right when starting.
