Script not works?

Hello I'm trying to make a loading gui but when the frame has reached (1.0, 0, 1, 0) it doesn't stop and i can't fint out how to fix it please help me here is the script

local prog = script.Parent
local gui = script.Parent.Parent.Parent.Parent.Parent
local frame = script.Parent.Parent.Parent.Parent
local lbarback = frame.LoadingBarBackground
local text = lbarback.Text
local textscript = lbarback.Text.Script
 
wait(0.8)
repeat
	prog.Size = prog.Size + UDim2.new(0.01, 0, 0, 0)
	wait(0.10)
until prog.Size == UDim2.new(1.0, 0, 1, 0)
 
while true do
	if prog.Size == UDim2.new(1.0, 0, 1, 0) then
		textscript.Disabled = true
		text.Text = "Loaded!!"
		wait(1.5)
		gui:Destroy()
	end
	wait(0.01)
end

Here is a picture Link

Not too sure if this is the problem, but try this. I just made a few adjustments.

local prog = script.Parent
local gui = script.Parent.Parent.Parent.Parent.Parent
local frame = script.Parent.Parent.Parent.Parent
local lbarback = frame.LoadingBarBackground
local text = lbarback.Text
local textscript = lbarback.Text.Script

wait(0.8)
repeat
	X1=prog.Size.X.Scale+.01 --Adds to the scale size
	prog.Size = UDim2.new(X1, 0, 1, 0) --Applies scale
	wait(0.10)
until prog.Size.X.Scale >=1

if prog.Size.X.Scale>1 then
	prog.Size=UDim2.new(1,0,1,0) --Assures that it's not too big
end

while true do
	if prog.Size == UDim2.new(1, 0, 1, 0) then
		textscript.Disabled = true
		text.Text = "Loaded!!"
		wait(1.5)
		gui:Destroy()
	end
	wait(0.01)
end

I think that this should work. If you have any further problems, please leave a comment below. Hope I helped :P
