Finish line script?

There is 2 players needed,

first problem is. I can't see it changing, but the other player can.

second is, i want when a player touches a part called finishline, they'll get teleported back to spawn

finishline brick.name = finishline btw

p = game.Players:GetChildren()

while true do
wait(.1)
if #p > 1 then
script.Parent.Text = "Starting."
wait(.25)
script.Parent.Text = "Starting.."
wait(.25)
script.Parent.Text = "Starting..."
wait(.25)
script.Parent.Text = "Starting.."
wait(.25)
script.Parent.Text = "Starting."
wait(.25)
script.Parent.Text = "Starting.."
wait(.25)
script.Parent.Text = "Starting..."
wait(5)
script.Parent.Text="Gotta go fast"
elseif #p < 1 then
script.Parent.Text = "1 more player is needed"
end
end
