Script not changing a text all of a sudden without any changes?

Hi there all,

I have a script and all of a sudden, with no changes made, one of the parts has stopped working. It used to work fine but for some reason it doesnt work anymore. It doesnt print any errors or info in the output. The script is below.

function Control(player,bn,ln,dc,ld)
	local rank = game.Players[player.Name]:GetRankInGroup(1096916)
	game.Players:FindFirstChild(tostring(player.Name)).PlayerGui.SpawnGUI.Finish.Status.Text = "The server is processing your request, please wait..."
	if rank ~= 0 then
		if rank ~= 2 then
			if ld == true and rank >2 then
				local count = table.getn(queue)
				table.insert(queue,tostring(player))
				table.insert(queue,bn)
				table.insert(queue,ln)
				table.insert(queue,dc)
				Spawn_ServerComms()
			elseif ld == false then
				local count = table.getn(queue)
				table.insert(queue,tostring(player))
				table.insert(queue,bn)
				table.insert(queue,ln)
				table.insert(queue,dc)
				Spawn_ServerComms()
			elseif ld == false and rank <2 then
				game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "You must be LD+ to drive this bus!"
			end
		else if rank == 2 then
			game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "You are suspended and cannot drive!"
		end
		end
	else 
		game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "Error: Server unauthorised your request."	
	end
end

receive = game.ReplicatedStorage:WaitForChild("Spawn_Client")
receive.OnServerInvoke = Control

The part in question is these parts, they don't do anything and the script doesn't break or return anything, it just no longer wants to change the text anymore.

game.Players:FindFirstChild(tostring(player.Name)).PlayerGui.SpawnGUI.Finish.Status.Text = "The server is processing your request, please wait..."

game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "You must be LD+ to drive this bus!"

game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "You are suspended and cannot drive!"

game.Players:FindFirstChild(tostring(player)).PlayerGui.SpawnGUI.Finish.Status.Text = "Error: Server unauthorised your request."

Any help is appreciated!

Many thanks :)

in your first line, you use "player.Name" in FindFirstChild,

game.Players:FindFirstChild(tostring(player.Name))

in all lines below, you use "player". I dont think you can FindFirstChild from a player object

game.Players:FindFirstChild(tostring(player)).
