Do you have a working code / is it giving you an actual error? If you think your code is ok, try testing your data store in Roblox rather than studios, as I’ve found data stores tend to not be consistant in Studios.
If you want to make sure that your code isn’t the problem you can use my datastore plugin as a template, the code in this plugin has been tested and works fine.
My code was not the problem, as playing the game out of studio finally gave a new result. (an error for the system I could not test because of roblox’s datastores)
