Script Issue: local MapsFolder = ServerStorage:WaitForChild("Maps") can any1 help me?

I am making a script for my own Roblox game but it says There is something wrong with this colomm local MapsFolder = ServerStorage:WaitForChild("Maps") And it says something about to close

Is this made in a Local Script or a Server Script? Local scripts run on the client, and the client can't access things on the server such as "ServerStorage" and "ServerScriptService". If you are trying to get stuff to the client, I would recommend using Remote Events.
