Why won't my button's equipped textlabel work?

I have a GUI shop that has buttons. The button's are there to buy weapons, when you own it and then click it again, it displays a text label "Equipped". I made a script so that it can show only one weapon already equipped, meaning once one button is clicked the text label of the button you clicked says "equipped", the other text labels that say equipped are invisible. The problem is that the equipped text labels aren't disappearing after clicking the buttons. What did I do wrong?

This is the equipped text label's script:

local player = game.Players.LocalPlayer
local sword = player:WaitForChild("PersonalSword")
if sword.Value == "Darkheart" then
	script.Parent.Visible = true
	
else
	script.Parent.Visible = false
end

This is the button's script:

local MarketplaceService = game:GetService("MarketplaceService")
local player = game.Players.LocalPlayer
local points = player:WaitForChild("leaderstats")["Player Points"]
local value = 2500 -- edit here
local name = "DarkHeartSword" -- here
local altname = "Darkheart"
local swords = script.Parent.Parent:GetChildren()
function TweenReceipt()
	local debounce = false
	
	if debounce == false then
		debounce = true
	script.Parent.Parent.Parent.MoneyNeeded.Visible = true
	script.Parent.Parent.Parent.MoneyNeeded.Amount.Text = value - points.Value
	script.Parent.Parent.Parent.MoneyNeeded:TweenPosition(UDim2.new(0, 300, 0, -100),"Out", "Quart", 1.5)
	wait(2.5)
	script.Parent.Parent.Parent.MoneyNeeded:TweenPosition(UDim2.new(0, 1300, 0, -100), "Out", "Quart", 0.2)
	script.Parent.Parent.Parent.MoneyNeeded.Position = UDim2.new(0, -1000, 0, -100)
	script.Parent.Parent.Parent.MoneyNeeded.Visible = false
	
	end
	debounce = false
end
script.Parent.MouseButton1Click:connect(function()
	if not player.Swords:FindFirstChild(altname) then -- edit here

		if points.Value >= value then -- buying clause
		points.Value = points.Value - value
		local Sword = Instance.new("BoolValue", player.Swords)
		Sword.Name = altname -- here
		script.Parent.Owned.Visible = true
		else
			TweenReceipt()
		end
	elseif script.Parent.Equipped.Visible == false then
		for i, v in pairs(swords) do
		if v.Name ~= name then
		v.Equipped.Visible = false
		script.Parent.Equipped.Visible = true
		player.Swords.Darkheart.Value = true -- edit here
		player.PersonalSword.Value = altname
		end
		end
		
	elseif script.Parent.Equipped.Visible == true then
	player.Swords.Darkheart.Value = false -- edit here too
	
	end
	
	
end)
if player:WaitForChild("Swords"):FindFirstChild(altname) then -- final edit
	script.Parent.Owned.Visible = true
end
