So, I've made the DataStore, and it's working fine. When I wanted it to print "Working" in the Output, it works, which means I've done the DataStore correctly. How would I display it inside a TextLabel? In this case, I got it so you have to touch a part, which is the parent of the script, for it to show the DataStore value. But, the textlabel doesn't do as told.
local datastore = game:GetService("DataStoreService"):GetDataStore("currency") game.Players.PlayerAdded:connect(function(player) local key = "user_"..player.userId datastore:UpdateAsync(key, function(oldcurrency) local newcurrency = oldcurrency or 0 return newcurrency end) end) game.Players.PlayerAdded:connect(function(player) script.Parent.Touched:connect(function() local key = "user_"..player.userId local coin = datastore:GetAsync(key) game.StarterGui.ScreenGui.Frame.TextLabel.Text = coin end) end)
The problem i see is that your attempting to change something in starterGui rather than the player's gui. So on line 15 replace it with
player.PlayerGui.ScreenGui.Frame.TextLabel.Text = coin
In order for a player to see a screen gui object, it has to be placed in a playergui which explains why it didn't work properly for you
