TextBox goes back to it's initial text?

I'm making a game with guis (screenguis) and when I place a text box in my gui when I change the text it randomly goes back to it's initial text. This has gotten very annoying and I can't find the source of the problem.

UPDATE; If it's a broken script, my script is working fine. But I'm gonna post it here anyways because I can't find any problems in my game.

local p = script.Parent.Parent.Parent.Parent.Parent
local as = game:GetService("AssetService")

script.Parent.MouseButton1Click:connect(function()
	local ds = game:GetService("DataStoreService"):GetDataStore("port--" .. script.Parent.Parent.add.Text)
	script.Parent.Parent.load.Visible = true
	local name = script.Parent.Parent.ipp.Text
	local place = nil
	script.Parent.Parent.load.ImageLabel.Image = "rbxassetid://234370067"
	script.Parent.Parent.load.TextLabel.Text = "Loading place..."
	if ds:GetAsync(name) == nil then
		place = as:CreatePlaceAsync("Building place", 518338357, "lol i got cr1pping d3pressi0nn..")
		ds:SetAsync(name, place)
	else
		place = ds:GetAsync(name)
	end
	script.Parent.Parent.load.TextLabel.Text = "Teleporting to place..."
	script.Parent.Parent.load.ImageLabel.Image = "rbxassetid://279548030"
	game:GetService("TeleportService"):Teleport(place, p)
end)

UPDATE 2; This script is a server script that's inside of a button.
