Gui timer button

Hello, I don’t know if it was understood but what I want to do is that when my character dies the time disappears, sorry for my bad English I am using the translator

I suggest doing the following;
When the player dies the time gets reset.
This should be a Local Script; a client-sided script

local plr = game:GetService("Players").LocalPlayer

plr.CharacterAdded:Connect(function(character)
	-- change the time of the timer back to what you started off with.
end)

sorry, I’m new to this, where do I put it?

You should put this inside your GUI script; just anywhere.
If you do not understand how this is supposed to work, then could you send us your you made script and put ``` before and after the script when you reply.
Note, I will be offline, so my responds will be late if any responds at all.
