How do I get other peoples Data in a localscript?

I tried invoking a specific player, but it didn't work If you need more information or more of the script please ask

Heres the LocalScript script

remotes.JpInfo.OnClientEvent:Connect(function(player)
	local yes, chances = remotes.GlobalJackpot:InvokeServer()
	local yesp = fr.Jackpot.Players
	local JackpotFrame = yesp:GetChildren()
	local playerb = game.Players:FindFirstChild(player.Name)
	
	local data = remotes.Jackpot:InvokeServer(playerb)
	local yes = game:GetService("ReplicatedFirst").PlayerName
		
	if not yesp:FindFirstChild(playerb.Name) then
		local Clone = yes:Clone()
		Clone.Parent = yesp
		Clone.Name = playerb.Name
		Clone.Player.Text = playerb.Name
		Clone.Added.Text = data.Added
	end

	local PlayerGui = game.Players.LocalPlayer.PlayerGui.MainGui.Frames.Jackpot.Players[playerb.Name]
	PlayerGui.Player.Text = playerb.Name
	PlayerGui.Added.Text = data.Added
end)

Heres how I get the data

Remotes.Jackpot.OnServerInvoke = function(player)
	local DataB = Data:get(player)
	return DataB
end
