Why is this hint script not working?

Hello, My friends...

Today im asking you why This Hint Script I have made doesn't work, I have classified everything into a proper group(s) etc...

And it isn't showing a Hint at all

Any Ideas why?

local h = Instance.new("Hint")
local sftg = game.ServerStorage.sft and game.Workspace.sft
local gftg = game.ServerStorage.gft and game.Workspace.gft
local obbyg = game.ServerStorage.obby and game.Workspace.obby

while wait() do
if sftg.Parent ~= game.Workspace and gftg.Parent ~= game.Workspace and obbyg.Parent ~= game.Workspace then
h.Parent = game.Workspace
h.Text = "Currently There is no map running..."
end
if sftg.Parent == game.Workspace and gftg.Parent ~= game.Workspace and obbyg.Parent ~= game.Workspace  then
	h.Parent = game.Workspace 
	h.Text = "Currently SwordFight is Running..."
end
end

if gftg.Parent == game.Workspace and sftg.Parent ~= game.Workspace and obbyg.Parent ~= game.Workspace then
	h.Parent = game.Workspace
	h.Text = "Currently GunFight is Running..."
end

if obbyg.Parent == game.Workspace and sftg.Parent ~= game.Workspace and gftg.Parent ~= game.Workspace then
	h.Parent = game.Workspace
	h.Text = "Currently Obby is Running..."
end

Try replacing wait() to true

BTW this is my first answer

The first line of the script is the problem. You stated that there was a new Hint, but you did not specify exactly where it is.

local h = Instance.new("Hint")

Instead, if you showed that it was somewhere in Workspace or another location, I'm sure it would work just fine.

local h = Instance.new("Hint", game.Workspace)
