FireClient not working and no errors showing up in output?

Hello, I finished writing this only for me to realize I'm not logged in when I clicked ask question so sorry if this seems a bit rushed but I am making 2 moves where when I press Q while having my mouse on the target I would be welded and teleported to them giving the illusion that im controlling them and the second move where when I press e while having my mouse over a target it would swap our positions it was working fine until I wanted to make it so that the victim being controlled wont be able to use moves when he is being controlled so I added a script that would add a bool value and when he gets controlled it would set it to true but when I added that and a few things to my scripts so it would detect if the bool is true or false it wont even work anymore, I put some print commands to see where is when it broke because it wont give any errors and it seems to break at the fire client part I dont really understand fireclient much so if im doing anything wrong with the fire client please let me know --output 1st. Got Passed Local script Controlled verify!, 2nd. Remote Event Call Received!, 3rd. Got passed character verify, 4th. Got passed Controlled Check!, 5th. Called Client Event! -- end of output It would say that it called the client but the client wont respond anything im doing wrong?

script to insert bool value (server script)

wait()
local char = script.Parent
wait()
local controlCheck = Instance.new("BoolValue")
controlCheck.Name = "ControlledCheck"
controlCheck.Value = false
controlCheck.Parent = char
wait(0.5)
script:Destroy()

script to check if player is being controlled only called when he uses a move (server script)

game.ReplicatedStorage.Remotes.Check.CheckControl.OnServerEvent:Connect(function(plr, Remote)
	print("Remote Event Call Received!")
	if plr.Character then
		print("Got passed character verify")
		local ControlledCheck = plr.Character:WaitForChild("ControlledCheck",5)
		if ControlledCheck.Value == false then
			print("Got passed Controlled Check!")
			game.ReplicatedStorage.Remotes.Check.CheckControl:FireClient(plr,false,Remote)
			print("Called Client Event!")
		elseif ControlledCheck.Value == true then
			print("Failed Controlled Event")
			game.ReplicatedStorage.Remotes.Check.CheckControl:FireClient(plr,true,Remote)
			print("Called failed event")
		end
	end
end)
