teleport player after leaderstat value is reached?

hi, im making an RPG based game. i have the leaderboard value of "lives" that tells the player how many lives they have. im trying to work out a script so that once the value of "Lives" reaches 0, it'll teleport the player to another area. heres what i got so far

local p = game.Players:GetChildren()
local stats = p:findFirstChild("leaderstats")       
local sp = stats:findFirstChild("Lives") 
if sp == nil then return false end                             
if (sp.Value == 0) then 
	for i = 1, #p do
		p[i].Character:MoveTo(Vector3.new(-37206.949, 516.942, -9.089))
		
	end
	end

this obviously doesnt work, but im trying to figure out how i should write to so that it'll teleport the players based on the Lives value. im also getting an error on line 2 for " attempt to call a nil value". what should i do?
