Issue with Datstore and string values?

So I'm getting an error saying

19:48:28.816 - ServerScriptService.Leaderboard:51: bad argument #3 to 'Value' (string expected, got boolean) 19:48:28.817 - Script 'ServerScriptService.Leaderboard', Line 51 19:48:28.817 - Stack End

The value's I'm trying to save are IntValue's and StringValue's

**Here's my script : **

-- ayy lmao 

local DSService = game:GetService("DataStoreService"):GetDataStore("PlayerSaveData")
game.Players.PlayerAdded:connect(function(plr)
	local uniquekey = "id-"..plr.userId
	
	local m = Instance.new("Model", plr)
	m.Name = "leaderstats"
	
	local i = Instance.new("IntValue", m)
	i.Name = "Cash"
	
	local w = Instance.new("IntValue", m)
	w.Name =  "Wins"
	
	local inb = Instance.new("BoolValue", plr)
	inb.Name = "InBattle"
	inb.Value = false
	
	local GB = Instance.new("BoolValue", plr)
	GB.Name = "GroupBonus"
	GB.Value = false
	
	local ID = Instance.new("BoolValue", plr)
	ID.Name = "IsDueling"
	ID.Value = true
	
	local Skin = Instance.new("StringValue", plr)
	Skin.Name = "CurrentSkin"
	Skin.Value = "ClassicSword"
	
	local MissingLink = Instance.new("StringValue", plr)
	MissingLink.Name = "MissingLink"
	MissingLink.Value = "false"
	
	
	if plr:IsInGroup(2852908) then
		if GB.Value == false then
			plr:WaitForChild('leaderstats'):WaitForChild('Cash').Value = plr:WaitForChild('leaderstats'):WaitForChild('Cash').Value + 500
			GB.Value = true		
		else
			end
	end
	
	
	local GetSaved = DSService:GetAsync(uniquekey)
	if GetSaved then
		i.Value = GetSaved[1]
		w.Value = GetSaved[2]
		GB.Value = GetSaved[3]
		Skin.Value = GetSaved[4]
		MissingLink.Value = GetSaved[5]
	else
		local NumbersForSaving = {i.Value, w.Value, GB.Value, ID.Value, Skin.Value, MissingLink.Value}
		DSService:SetAsync(uniquekey, NumbersForSaving)
	end
end)

game.Players.PlayerRemoving:connect(function(plr)
	local uniquekey = "id-"..plr.userId
	local Savetable = {plr.leaderstats.Cash.Value, plr.leaderstats.Wins.Value, plr['GroupBonus'].Value, plr['IsDueling'].Value, plr['MissingLink'].Value, plr['CurrentSkin'].Value}
	DSService:SetAsync(uniquekey, Savetable)
end)
