Advance Quest system for a story game [HELP]

the script is case-sensitive, do TweenService instead of Tweenservice


dk if i put it in right place or what but i was assuming there

why did you try to get a service by making a tweenservice setup???
i meant to say to replace the line of code i mentioned earlier to
local Tweenservice = game:GetService(“TweenService”), not to change :Create() to :GetService()
