The rest of the script after elseif doesn't work

I would like me to be able to close the door using the ‘Closedoor’ command

The only problem is that after the ‘elseif’ in my script everything stops working and the ‘Closedoor’ command does not work.

I tried adding and subtracting ‘end’ and tried splitting the commands into two scripts however this makes me only able to open the door once and only once close it after this nothing works anymore even I can’t open it anymore. I couldn’t find any topics on this subject.

local GroupId = 5243321
local MinimumRank = 254

local adornee = false
local open = false

local ticks = script.Tick.Value

local modelleft = script.Parent.Left
local modelright = script.Parent.Right

game.Players.PlayerAdded:Connect(function(Player)
        Player.Chatted:Connect(function(Message)
                if Player:GetRankInGroup(GroupId) >= MinimumRank then
                        if Message == "Opendoor" then
                                print("Activated")


                                        if adornee == false then
                                                if open == false then
                                                        adornee = true
                                                        print("not open")
