'SetAsync is not a valid member of IntValue'. Can Somebody Help ?

Hello

I Am Making A Custom Character Save System And I Get This Error

SetAsync is not a valid member of IntValue

Here is the code (Shortened, full version is not complete)

local CCDS1 = game:GetService("DataStoreService")
local Saveslot1 = CCDS1:GetDataStore("CCData1")

game.Players.PlayerAdded:connect(function(player)
    local slot1 = Instance.new("Folder",player)
    slot1.Name = "CustomCharacterSlotOne"
    local skincolorG = Instance.new("IntValue",slot1)
    skincolorG.Name = "SkinColorGREEN"
    skincolorG.Value = Saveslot1:GetAsync(player.UserId) or 0
    skincolorG:SetAsync(player.UserId, skincolorG.Value)
    skincolorG.Changed:connect(function()
        Saveslot1:SetAsync(player.UserId, skincolorG.Value)
        print("skincolorG saved !")
    end)
end)

Can You Tell Me Why Is This Not Working ?

Edit : Solved ! Thanks mattscy :)
