How do you make a button that saves leaderstats into DataStores?

Hello everyone, I've read the Roblox Wiki on all of the items used below, but when the script is run, it returns no error and all print()'s are printed. Anyone know why it just refuses to save? :)

Button script:

local serversave = game.Workspace:WaitForChild("ServerSave")

function onClicked()
    script.Parent.Parent.Status.Text = "Saving..." -- just for looks
    print("Sending Save Request...")
    serversave:InvokeServer(player) -- triggering server script since button script is not a server script
    print("Sent Save Request!")
    wait(2) -- everything after this is just for looks
    script.Parent.Parent.moolah.number.Text = game.Players.LocalPlayer.leaderstats.Money.Value
    script.Parent.Parent.bb.number.Text = game.Players.LocalPlayer.leaderstats.BuildingBux.Value
    script.Parent.Parent.xp.TextLabel.Text = "EXP Level: "..game.Players.LocalPlayer.leaderstats.Level.Value
    script.Parent.Parent.Status.Text = "Saved!" -- This is just for me so that there were no errors occurring in the above
end
script.Parent.MouseButton1Click:connect(onClicked)

Save Script inside ServerScriptService:

local serversave = Instance.new("RemoteFunction") -- making the RemoteFunction
serversave.Name = "ServerSave"
serversave.Parent = game.Workspace

local DS = game:GetService("DataStoreService"):GetDataStore("leaderstats")

serversave.OnServerInvoke = function(player) -- run when button is pressed and the remote function is called(?)
    local key = "plr-"..player.userId

    local Money = player.leaderstats.Money
    local BB = player.leaderstats.BuildingBux
    local Level = player.leaderstats.Level

    print("Attempting to Server Save...")
    DS:SetAsync(key, {Money.Value, BB.Value, Level.Value}) -- table?
    print("Server Saved!") -- this does get printed and no errors are in output.
end
