How can I make this door open when 1 player gets near it instead of all?

I've been working on an automatic door and I cannot get this right. When all the players in the server get near the door, the door opens otherwise if only 1 player gets near the door it just shuts and closes over and over. It has something to do with this part:

players = game.Players:children()
for i = 1,#players do
if (players[i].Character.Torso.Position - sensor.Position).magnitude <=  dist

Full script: (Unnecessary parts removed)

sensor = workspace.autodoor.sensor
while true do
wait(0.1)
dist = 25

players = game.Players:children()
for i = 1,#players do
if (players[i].Character.Torso.Position - sensor.Position).magnitude <=  dist and script.Parent.Open.Value == false then
script.Parent.Open.Value = true
--[[ Stuff that makes the door open]]

elseif players[i].Character.Torso.Position - sensor.Position).magnitude >=  dist and script.Parent.Open.Value == true then
script.Parent.Open.Value = false
--[[ Stuff that makes the door close]]

end
end
end
