Opening And closing gui not working?

i am making a new sim game gui only, and i'm trying to make windows open and close but it isn't working.

script.Parent.MouseButton1Click:connect(function(Click)
 
script.Parent.Parent.Parent.Stuf.Click:Play()
if script.v.Value = false then
	script.Parent.Parent.Parent.pop1.Visible = true
	script.v.Value = true
else
	if script.v.Value = true then
		script.Parent.Parent.Parent.pop1.Visible = false
		script.v.Value = false
	end
end


end)

Getting this in output

11:53:08.180 - Players.Player1.PlayerGui.ScreenGui.Frame.Frame.ImageButton.ButtonDownGui:7: 'then' expected near '='
