User not getting badge because cant find user through int64?

This LocalScript inside a TextButton is supposed to award a badge to a users id, that the player chooses, due to a text label holding text of a player, and the local script should award the badge to that player name in the text label. i get an error saying it cant find anything in int64

local bs = game:GetService("BadgeService")
local ps = game:GetService("GamePassService")
local pass = 9289382
local badge = 0000000
local playert = script.Parent.Parent.thename
local player = game.Players.LocalPlayer
local UserId = game.Players.LocalPlayer.UserId
local useridt = playert.Text..UserId

pass = false

if ps:GetChildren(player.UserId, pass) then 
	pass = true
	if pass == true then
		script.Parent.Text = "Multiplier Die"
		script.Parent.MouseButton1Click:Connect(function()
			bs:AwardBadge("playert"..useridt, badge)
	game:GetService("Players").LocalPlayer.PlayerGui.GiveDie.Enabled = false and game:GetService("Players").LocalPlayer.WhichGive.Enabled == false
		end)
	end
end

The first argument of :AwardBadge() has to be a UserId by itself. Secondly, badges can only be awarded by the server.
