I can't seem to make my place auto update with PlaceVersion (Property)?

So I'm trying to make it so that when PlaceVersion changes after I enforce an update, it will shutdown all the servers without me having to press shutdown and everyone wondering what just happened. But this script does not seem to work, Game.PlaceVersion.Changed:connect(update) does not work.

//SCRIPT

script.placeversion.Value = game.PlaceVersion
print(script.placeversion.Value)

function update()
wait()
print("The CURRENT Version is "..game.PlaceVersion)
print("The OLD Version is "..script.placeversion.Value)
if Game.PlaceVersion > script.placeversion.Value then
print("Got past the if statement")
Game.Workspace.Main.Disabled = true
Game.Workspace.RecreateMain.Disabled = true
Game.Lighting.Alert.Value = "Updates were found; the server will now shutdown to enforce them."
wait(3)
Game.Lighting.Alert.Value = "Check the description to see what's new!"
wait(3)
for i = 1,5 do
wait(1)
Game.Lighting.Alert.Value = "Shutting down in about "..5-i.." Seconds."
end
wait(0.8)
for a,c in ipairs(Game.Players:GetChildren()) do
wait()
c:Kick()
end
end
end

Game.PlaceVersion.Changed:connect(update)

I even tried to do it like this but it still didn't work.

script.placeversion.Value = game.PlaceVersion
print(script.placeversion.Value)

repeat wait(1) until Game.PlaceVersion ~= script.placeversion.Value
wait()
print("The CURRENT Version is "..game.PlaceVersion)
print("The OLD Version is "..script.placeversion.Value)
if Game.PlaceVersion > script.placeversion.Value then
print("Got past the if statement")
Game.Workspace.Main.Disabled = true
Game.Workspace.RecreateMain.Disabled = true
Game.Lighting.Alert.Value = "Updates were found; the server will now shutdown to enforce them."
wait(3)
Game.Lighting.Alert.Value = "Check the description to see what's new!"
wait(3)
for i = 1,5 do
wait(1)
Game.Lighting.Alert.Value = "Shutting down in about "..5-i.." Seconds."
end
wait(0.8)
for a,c in ipairs(Game.Players:GetChildren()) do
wait()
c:Kick()
end
end
