If I have a folder and I want to place a value(Ex: NumberValue's) into it and have several scripts read from it where is the best place to put that folder, without getting any errors client or server side?
Well, the short answer is that it depends.
You have to ask yourself a few questions. Do I want both the server and the client to access these values, or do I only want the server to access these values?
If you only want the server to be able to see your values, store them in ServerStorage
.
If you want the server and the client to be able to see your values, store them in ReplicatedStorage
. (See ServerStorage and ReplicatedStorage on the Wiki.
