How to make it when a user comes in contact with PointLight it kills them and opens a gui?

This is for my new RPG game

In an infinite loop check for player distance from the part, since PointLight spreads in all directions

while wait() do
	for k,v in next, game.Players:GetPlayers() do
		if v:DistanceFromCharacter(script.Parent.Position) <= script.Parent.PointLight.Range then
			v.Character.Humanoid.Health = 0
		end
	end
end

Hi, FancyClone! Try using functions, to be exact, the onTouched function. Here is your syntax:

--Put the follow script into the part the pointLight is in, and edit to your choice.

function onTouched(hit)
	--Here is your part. Try to see if you can find how to delete the part your player touches, and --bring up a GUI. I am not giving you the full answer as this website is not for requesting, but for help.
end
script.Parent.Touched:connect(onTouched)
