How can I constantly check 2 values at once?

Help and Feedback Scripting Support
#1

I am trying to constantly check if 2 players are on a spot at the same time, they get on the spot by using a ProximityPrompt. And when the players are both on the spot, it should teleport them to a designated location, written as “rInGameTP”/bInGameTP"

this is my code.

	rPrompt.Triggered(function(rPlr)
		if bTaken.Changed or rTaken.Changed then
			if bTaken.Value == true and rTaken.Value == true then
			print('Game 1 Ready')
			wait(1)
			bPlr.Character:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(BInGameTP.Position)
				rPlr.Character:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(RInGameTP.Position)
			end
		end
	end)
end)

You could insert the player into a table [if he is not there],
And when another player triggers the prompt, check if any player inside that table is at the same spot as this current player.

local otherPlayer = nil

proximityPrompt.Triggered:Connect(function(player)
    if otherPlayer == nil then
        -- set over player to the player that triggered the prompt
        otherPlayer = player
        -- wait 1 second
        task.wait(1)
        -- if the other player is no longer this player then exit
        if otherPlayer ~= player then return end
        -- set other player to nil
        otherPlayer = nil
    else
        -- teleport the 2 players
        player.Character.PrimaryPart.CFrame = BInGameTP.CFrame
        otherPlayer.Character.PrimaryPart.CFrame = BInGameTP.CFrame
        -- set otherplayer to nil
        otherPlayer = nil
    end
end)
