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
