Ex: I am trying to add something in table1 to table2 then print the results In lines 30, 42,48 are where I use this example it adds xpLvlTable to the table that is stored in 'DataStore'

-- 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)
    -- Defines xp and lvl
    local key = 'Player-'..plr.userId
    local xpLvlTable = xp_lvlDataStore:GetAsync(key)
    local curXp = xpLvlTable[1]
    local curLvl = xpLvlTable[2]
    print('serverCurXp = '..curXp)
    print('serverCurLvl = '..curLvl)
    -- Fire to player
    xpChanger:FireClient(plr,xpToAdd)
    -- Math
    local newLvl = curLvl + 1
    local newXp = curXp + xpToAdd
    local lvlEquation = 10*curLvl
    print('ServerNewXp = '..newXp)
    -- Adds lvls and sets xp
    if curLvl == 0 and newXp >= 10 then
        print('Saving 1st lvl')
        local new_xpLvlTable = {1,(xpToAdd - 10)}
        wait(6)
        xp_lvlDataStore:IncrementAsync(key,(new_xpLvlTable))
        print('Saved')
    elseif curLvl >= maxLvl then
        print('Saving maxLvl')
        local xpLvlTable = {0,350}
        wait(6)
        xp_lvlDataStore:SetAsync(key,(xpLvlTable))
        print('Saved')
    elseif lvlEquation <= newXp and lvlEquation ~= 0 then
        print('Saving Lvled Up')
        local xpLvlTable = {1,xpToAdd - lvlEquation}
        wait(6)
        xp_lvlDataStore:IncrementAsync(key,(xpLvlTable))
        print('Saved')
    else
        print('Saving Did not lvl up')
        local xpLvlTable = {curLvl,xpToAdd}
        wait(6)
        xp_lvlDataStore:IncrementAsync(key,(1))
        print('Saved')
    end
end))

I meant to use one table and its numbers that are in it to be added to the numbers inside the second table

-In short they are tables that go inside other tables, they also have more "power" than regular tables as they can execute functions.

Yep. Just add the table as you would for any other element.

local table1 = {"apple", "banana", "pommegranate", "idk if that spelling is right"}
local table2 = {1, 3, "hello", table1}

-- same thing as saying

table2 = {1, 3, "hello", {"apple", "banana", "pommegranate", "idk if that spelling is right"}}

-- to get table1 from table2
table1 = table2[4] -- table is the 4th index

-- to get the first element of table 1 from table 2
local firstElement = table2[4][1] --> "apple"

-- alterantively
table1 = table2[4]
firstElement = table1[1] --> "apple"

Hope this helps! :)

Added as in operationally? Like 3 + 5 so the result is 8? Or add as in concatenate the contents of the table? chomboghai 2044 — 6y
