Im trying to make an outfit loading system but im struggling to create a queueing system like the one below:

How would i go around implementing a system like this?

Here is my existing code:

local httpService = game:GetService("HttpService")
local baseUrl1 = "https://avatar.roblox.com/v1/users/"
local baseUrl2 = "/outfits?itemsPerPage=50"
local requests = {}
local proxyHttp = require(game.ServerScriptService.ProxyRobloxAPI:Clone())



local checkPlayer = function()
	if #requests >= 1 then
		local userId = (requests[1])
		table.remove(requests, table.find(requests, userId))
		local s, x = pcall(function()
			local data = proxyHttp:GetAsync(baseUrl1..userId..baseUrl2)
			if data then
				game.Workspace.Map.Outfits:ClearAllChildren()
				local outfits = data.data
				for i, v in pairs(outfits) do
					local desc = game.Players:GetHumanoidDescriptionFromOutfitId(v.id)
					local c = game.ServerStorage.BaseAvatar:Clone()
					c.Name = v.name
					c.Parent = workspace.Map.Outfits
					c.HumanoidRootPart.Position = Vector3.new(-123 + (5 * (#workspace.Map.Outfits:GetChildren() - 1)), -5, -59.5)
					c.Humanoid.NameDisplayDistance = 50
					c.Humanoid:ApplyDescription(desc)
					c.HitBox.Position = c.HumanoidRootPart.Position
				end
			end
		end)
		if not s and x then warn(x) end
	end
end


local loop = function()
	while true do
		wait(7.5)
		if #requests >= 1 then
			checkPlayer()
		else
			repeat game:GetService("RunService").Heartbeat:Wait() until #requests >= 1
		end
	end
end

game.ReplicatedStorage.RequestUser.OnServerInvoke = function(plr, targetName)
	local s, x = pcall(function()
		local targetUserId = game.Players:GetUserIdFromNameAsync(targetName)
		if targetUserId ~= nil then
			local isOnRequests = false
			for i, v in pairs(requests) do
				if v == targetUserId then
					isOnRequests = true
					break
				end
			end
			if isOnRequests == false then
				table.insert(requests, targetUserId)
				if #requests == 1 then
					checkPlayer()
				end
				return "Put in queue!"
			else
				return "User is already on list!"
			end
		else
			return "User doesn't exist!"
		end
	end)
	if not s and x then warn(x) end
end

coroutine.wrap(loop)()

Client Code:

local players = {}
game.ReplicatedStorage.GetQueue.OnClientEvent:Connect(function(requests, currentid, targetusername, isrunning)
	for _,v in pairs(requests) do
		
	
		table.insert(players, v)
		
		
		local clone = game.ReplicatedStorage.QueueExample:Clone()
		print("yes")
		clone.Name = targetusername
		clone.Username.Text = targetusername
		clone.Parent = script.Parent.Frame.Frame.Folder
		
		--How do i remove from the table when #"requests" changes
	end
end)

since you have a equals sign its gonna do 2 what you need to do is
if #requests > 1 then
