Why won't my script won't recognise that a Gui is open?

local Fix = script.Parent.Parent.Parent:WaitForChild("Fix")

local PrestigePanelIsOpen = game.Workspace:WaitForChild("PrestigePanelIsOpen")

local Frame = script.Parent.Parent.Parent:WaitForChild("Frame")

local ClosePanel = script.Parent.Parent.Parent:WaitForChild("ClosePanel")

Fix.Event:Connect(function()

PrestigePanelIsOpen = "true"

end)

if PrestigePanelIsOpen.Value == "true" then

while true do

print("it is open") --this is not printed

script.Parent.MouseButton1Click:Connect(function(click)

Frame.Visible = false

Frame.Active = false

PrestigePanelIsOpen.Value = "false"

ClosePanel:Fire()

end)

end

wait(0.1)

end This script closes a GUI. It was working before then my studio crashed and I lost it :(
