Ban script not kicking me from the game?

I made a script to ban players, when you press ban on a gui it is supposed to kick you from the game but it doesn't, why not?

-- UI Variables
local frame = game.StarterGui:WaitForChild("BanPanel"):WaitForChild("Frame")
local nameBox = frame.Name
local reasonBox = frame.Reason
local banButton = frame.Ban
local timeBox = frame.Time

-- Ban player function
function banPlayer()

    local playerToBan = game.Players:FindFirstChild(nameBox.Text)

    -- Epoch time to unban
    local convertedTime = tonumber(timeBox.Text)
    local numTime = convertedTime * 86400
    local unbanTime = os.time() + numTime
    print(unbanTime)

    -- Create a banned tag
    local banTag = Instance.new("BoolValue")
    banTag.Name = "Banned"
    banTag.Parent = playerToBan

    -- Kick player
    playerToBan:Kick("You are banned for"..timeBox.Text.." days:"..reasonBox.Text.." is not aloud in Silencer.")

    print(playerToBan.Name.." has been banned from the game")

    return unbanTime
end

-- Click to ban

local returnedBanTime

banButton.MouseButton1Click:Connect(function()
    returnedBanTime = banPlayer()
end)

I think it might be kind of obvious what this is supposed to do but when I click the ban button it does nothing
