Why is my 5 value checking script won't work if the player makes those 5 values true?

So, I've wanted to do a multiple(5) condition checks, in a script. Basically there's 5 values in different parts and if the proximityprompts trigger they change 1 value, and there are 5 of those, and if those 5 values are all true, then it should play the animation and the sound. But the problem is: if i tell the script to change every value on its own like:

value5.Value = true
value4.Value = true
value3.Value = true
value2.Value = true
value1.Value = true

Then it's working but I wanted so if the player activates all of the values with the proximity prompt then it should play the animation,etc... Here's the script:

local ws = game.Workspace

local value1 = ws.firstvalve.Value
local value2 = ws.secondvalve.Value
local value3 = ws.thirdvalve.Value
local value4 = ws.fourthvalve.Value
local value5 = ws.fifthvalve.Value

local TweenService = game:GetService("TweenService")

local door = workspace.Bigmetaldoor
local doorRoot = door.PrimaryPart

local DoorSwingInfo = TweenInfo.new()

local DoorSwingTween = TweenService:Create(doorRoot, DoorSwingInfo, {
    CFrame = doorRoot.CFrame * CFrame.Angles(0, math.rad(-35),0)
})

local opensound = game.Workspace.Bigmetaldoor.Door.metaldooropen

print("start")

if value1.Value == true and value2.Value == true then
        script.firstsecond.Value = true
        print("count")
    end

if value3.Value == true and value4.Value == true then
        script.thirdfourth.Value = true
        print("count")
    end

if script.thirdfourth.Value == true and value5.Value == true then
        script.firstfifth.Value = true
        print("count")
end

if script.firstsecond.Value == true and script.thirdfourth.Value == true then
        script.second.Value = true
        print("count")
    end

if script.second.Value == true and script.firstfifth.Value == true then
        script.all.Value = true
        print("count")
    end

if script.all.Value == true then

        DoorSwingTween:Play()
        opensound:Play()    
        print("done")
    end

Thanks for reading, and all the helping that you guys give! I'm very thankful!
