Why can't I send a trade request to someone more than once?

So I'm trying to make a trading system and right now I'm working on getting the trade system to able to send a trade request to the player. I added a decline button (aka it deletes the gui) and such. Here's the script: Local script:

local remote = game.ReplicatedStorage.TradingRemotes:WaitForChild("TradeRequest")
end)
local debounce = false
local gui = script.Parent.Parent:WaitForChild("Thingy")
script.Parent.MouseButton1Down:Connect(function()
    if debounce == false then
        debounce = true
    local player2 = gui.Text --other player
    local players = game:GetService("Players")
    local player1 = players.LocalPlayer
        remote:FireServer(player2)
        wait(1)
        debounce = false
end
        end)

Server Script:

local rp = game:GetService("ReplicatedStorage")
local remote = rp.TradingRemotes:WaitForChild("TradeRequest")
remote.OnServerEvent:Connect(function(player1, player2)
    local players = game:GetService("Players")
    if players:WaitForChild(player2).PlayerGui:FindFirstChild("MoreTrade") then return end
    if player2 == player1.Name then return end
    local guifolder = game.ServerStorage:WaitForChild("TradeGuis")
    local gui = guifolder:WaitForChild("MoreTrade"):Clone()
    gui.Parent = players:WaitForChild(player2).PlayerGui
    gui.Frame.PlayerName.Text = "Incoming trade request from "..player1.Name
end)

It's supposed to not give the gui if it is in player2's playergui, but when I test, it only does it once, and not again, meaning, I send a trade request to player2, he gets the trade request but declines it, now player1 can't send a trade request to him anymore for some reason. Any help is appreciated.
