Variable is not updating when I change it in Roblox Studio Lua

Question

This is the code:

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"

    money = Instance.new("IntValue")
    money.Name = "Money"
    money.Parent = leaderstats
    money.Value = 0
    ---------------------------------------------------------------------
    multiplier = Instance.new("IntValue")
    multiplier.Name = "Multiplier"
    multiplier.Parent = player
    multiplier.Value = 1.0
    ---------------------------------------------------------------------
    leaderstats.Parent = player
end) : 

workspace:WaitForChild("Upgrades"):WaitForChild("Upgrade_1"):WaitForChild("ClickDetector").MouseClick:Connect(function(player)
    workspace:WaitForChild("Upgrades"):WaitForChild("Upgrade_1"):WaitForChild("ClickDetector"):Destroy() -- Removes ClickDetector
    local money = player:WaitForChild("leaderstats"):WaitForChild("Money")
    ---------------------------------------------------------------------    ---------------------------------------------------------------------
    while True wait(0.025) do
        local currentMultiplier = player:WaitForChild("Multiplier").Value
        money.Value = money.Value + (1.0 * currentMultiplier)  
    end
end)

The problem is that when I change the multiplier.Value in Roblox Studio, it doesn't change in the code. However, when I change it in the code, it works fine. I don't know how to get the code to update when I change the variable manually in Roblox Studio.

One of my theories is that money.Value is not checking if the variable changed while the loop is running.
