Change radius to click detector?

i found this door script that opens two doors when the player is near, but how would i go about changing it from seeing if the player is near to just the player clicking a button and the doors opening?

script:

local Open = false
local Radius = 10

function MoveDoors(mod)
	for i = 1, 10 do
		script.Parent.DoorA.Mesh.Scale = script.Parent.DoorA.Mesh.Scale + Vector3.new(-.1 * mod, 0, 0)
		script.Parent.DoorB.Mesh.Scale = script.Parent.DoorB.Mesh.Scale + Vector3.new(-.1 * mod, 0, 0)
		script.Parent.DoorA.Mesh.Offset = script.Parent.DoorA.Mesh.Offset + Vector3.new(.2 * mod, 0, 0)
		script.Parent.DoorB.Mesh.Offset = script.Parent.DoorB.Mesh.Offset + Vector3.new(-.2 * mod, 0, 0)
		wait()
	end
	script.Parent.DoorA.CanCollide = mod == -1
	script.Parent.DoorB.CanCollide = mod == -1
end

while wait(.5) do
	local openning = false
	for _, v in pairs(game.Players:GetPlayers()) do
		if v:DistanceFromCharacter(script.Parent:GetModelCFrame().p) < Radius then
			openning = true 
		end
	end 
	if openning and not Open then
		MoveDoors(1)
		Open = true
	elseif not openning and Open then
		Open = false
		MoveDoors(-1)
	end
end

make a model with a door shut and 2 doors that are open its your job to make the button and where it is located name the closed door ClosedDoor name the left open door LeftDoorOpen name the right open door RightDoorOpen add a script (located below) to the button and a click detector to the button group eveything together

local ButtonPart = script.Parent.Parent.ButtonPart
local DoorsShut = script.Parent
local LeftDoorOpen = script.Parent.Parent.LeftDoorOpen
local RightDoorOpen = script.Parent.Parent.RightDoorOpen
local clickdetector = script.Parent.Parent.ButtonPart.ClickDetector

clickdetector.MouseClick:Connect
DoorsShut.Transparency = 1
DoorsShut.CanCollide = false
LeftDoorOpen.Transparency = 0
RightDoorOpen.Transparency = 0
LeftDoorOpen.CanCollide = true
RightDoorOpen.CanCollide = true
wait(1.5)
DoorsShut.Transparency = 0
DoorsShut.CanCollide = true
LeftDoorOpen.Transparency = 1
RightDoorOpen.Transparency = 1
LeftDoorOpen.CanCollide = false
RightDoorOpen.CanCollide = false
end
