Issue with strings and a table..?

Okay so I have this table:

local defaultdatas = {
	Enchantments = 0
	Slot1 = 0,
	Enchantments1 = 0,
	Slot2 = 0,
	Enchantments2 = 0,
	Slot3 = 0,
	Enchantments3 = 0,
	Slot4 = 0,
	Enchantments4 = 0,
	Slot5 = 0,
	Enchantments5 = 0
	
}

Then this line of code

local DataStore = game:GetService("DataStoreService")
local HttpService = game:GetService("HttpService")
local ds = DataStore:GetDataStore("Playerdata")
game.Players.PlayerAdded:connect(function(player)
    local datas = ds:GetAsync(player.UserId)
if datas then	
    datas = HttpService:JSONDecode(datas)
else
	datas = defaultdatas
	end
    
    local data = Instance.new("Folder",player)
    data.Name = "Data"
local numberofslots = 5
local slotcurrentlyat = 1
for i = 1, numberofslots do
	local slot = Instance.new("StringValue", data)
	slot.Name = "Slot"..slotcurrentlyat
	slot.Value = data["Slot"..slotcurrentlyat] or defaultdatas["Slot"..slotcurrentlyat]
	local enchantments = Instance.new("StringValue", data)
	enchantments.Name = "Enchantments"..slotcurrentlyat
	enchantments.Value = data["Enchantments"..slotcurrentlyat] or defaultdatas["Enchantments"..slotcurrentlyat]
	slotcurrentlyat = slotcurrentlyat + 1
	wait()
	end
end)

Apparently the only issues are:

enchantments.Value = data["Enchantments"..slotcurrentlyat] or defaultdatas["Enchantments"..slotcurrentlyat]

and

slot.Value = data["Slot"..slotcurrentlyat] or defaultdatas["Slot"..slotcurrentlyat]

also this error

ServerScriptService.Data:19: bad argument #3 to 'Value' (string expected, got Object)

obv this isn't the whole script, but these are the only parts linked to the issue I have. Please help.
