Why won't a block change color when stepped on?

I have a checkpoint block here and inside it I put for the block to change color when stepped on. #1 The block is not changing color when stepped on, #2 I need the GetPropertyChangeSignal to trigger the award function.

local myspawn = script.Parent
local serverStorage = game:GetService('ServerStorage')
local levelupreal = Instance:FindFirstChild('levelup')
local function award(player, level, bucks)
    local stats = player:findFirstChild('touch')
    local Money = player:findFirstChild("leaderstats")

    local EarnMoney = Money and Money:findFirstChild('ObbyBucks<|>')
    local levelStat = stats and stats:findFirstChild('levelup')
    if levelStat then
        local levelStatValue = levelStat.Value + level
    if EarnMoney then
        local EarnMoneyValue = EarnMoney.Value + bucks
    end
    end
end

myspawn.Touched:Connect(function(hit)
    if hit and hit.Parent and hit.Parent:findFirstChild("Humanoid") then
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        local checkpointData = serverStorage:findFirstChild("CheckpointData")
        if not checkpointData then
            checkpointData = Instance.new("Model", serverStorage)
            checkpointData.Name = "CheckpointData"
        end
        local checkpoint = checkpointData:findFirstChild(tostring(player.userId))
        if not checkpoint then
            checkpoint = Instance.new("ObjectValue", checkpointData)
            checkpoint.Name = tostring(player.userId)
            player.CharacterAdded:connect(function(character)
                wait()
                local HumanoidRootPart = character:WaitForChild("HumanoidRootPart")
                HumanoidRootPart.CFrame = serverStorage[tostring(player.userId)].Value.CFrame
                + Vector3.new(0, 4, 0)
            end)
        end
        myspawn.BrickColor = BrickColor.new(23)
        checkpoint.Value = myspawn
        myspawn.GetPropertyChangeSignal("BrickColor"):Connect(award(player, 1, 10))
    end                                                                               
end)
