Datastore saving intvalue but not its value

Help and Feedback Scripting Support
#1

Im trying to make a data store which stores the skills learned and their cost as the value, the skill is being saved and loaded properly, but not its value. For example, the skill name loads on the right place, but its value is set to 0, regardless of what it was before quitting the game.
edit: oops forgot a piece of the code

function save(player)
	if player then
				
		local unlockedskills = {}
		
local dataTree = game:GetService("DataStoreService"):GetDataStore("skilltree4")
	
		for i, v in pairs(player:WaitForChild("unlockedskills"):GetChildren())do
			unlockedskills[v.Name] = v.Value
		end
			
		dataTree:SetAsync(player.UserId, unlockedskills)
 end
end
game.Players.PlayerAdded:Connect(function(plr)
	local unlockedskills = Instance.new("Folder", plr)
	unlockedskills.Name = "unlockedskills"

	local success, errom = pcall(function()
		local loadskills = dataTree:GetAsync(plr.UserId)
		if loadskills then
			print(loadskills)
			for i,v in pairs(loadskills)do
				local skill = Instance.new("IntValue", unlockedskills)
				skill.Name = i
end
end
end)
end)
game:BindToClose(function()
	for i, v in pairs(game.Players:GetChildren())do --NORMAL SAVE GAME CLOSE
		save(v)
	end
end)

--[[game:BindToClose(function()
	if game:GetService("RunService"):IsStudio() then
		for i, v in pairs(game.Players:GetChildren())do --STUDIO SAVE GAME CLOSE
			save(v)
		end
	end
end)
]]

game.Players.PlayerRemoving:Connect(function(plr)
	if game:GetService("RunService"):IsStudio() then --STUDIO SAVE PLAYER QUIT
		save(plr)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr) --NORMAL SAVE PLAYER QUIT
		save(plr)
end)

Did you forget to assign skill.Value? Also, in this piece of code;

game.Players.PlayerRemoving:Connect(function(plr)
	if game:GetService("RunService"):IsStudio() then --STUDIO SAVE PLAYER QUIT
		save(plr)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr) --NORMAL SAVE PLAYER QUIT
		save(plr)
end)

Both playerremoving events will fire wether your in game or in studio, so it’s better to just have one instead.

I feel like an idiot now, putting this worked

		local loadskills = dataTree:GetAsync(plr.UserId)
		if loadskills then
			print(loadskills)
			for i,v in pairs(loadskills)do
				local skill = Instance.new("IntValue", unlockedskills)
				skill.Name = i
				skill.Value = v

Although i have a question, just how many stores are recommended? For example, if i had a datastore for player skills and another one for weapon skills, would it cause any issues?

You can save both player skills and weapon skills into one datastore.
