Can you help me fix the error: attempt to call local "xpLvlTable" (a table value)? [SOLVED]

I get the error attempt to call local "xpLvlTable" (a table value) and I have a metatable inside the table that is activated with __call when the table is called

'Script'

-- Variables
local xp_lvlDataStore = game:GetService('DataStoreService'):GetDataStore('xp/lvlStore')
local repStorage = game:GetService('ReplicatedStorage')
local xpChanger = repStorage:WaitForChild('Xp_LvlChanged')
local xpToAdd = 5
local part = script.Parent
local maxLvl = 350

-- Events
pcall(part.ClickDetector.MouseClick:Connect(function(plr)
    local key = 'Player-'..plr.UserId
    local xpLvlTable = xp_lvlDataStore:GetAsync(key)
    -- Fire to player
    xpChanger:FireClient(plr,xpToAdd)
    -- Sends added xp then saves
    xpLvlTable(xpToAdd)
end))

It errors on line 16

'Table'

-- sets the xp to 0 if plr is new
