What's luck got to do with it?!?

I am doing some simple freelance work and every once in a while I need to get down and dirty with administration and contacts with the "authorities". I am about to register a trade mark and after a few hundred mouse clicks on prv.se and bolagsverket.se (I can guarantee that there has been no user testing made for these sites what so ever) I stumbled across, by a fluke, an online form. Great!

What amazes me is that the instruction for the form ends with "Good luck". Why on earth would you need luck to fill out a form?! Are the cells jumping back and forth? Do you have to guess what they are asking for? What? As you can imagine I have not tried to fill out the form yet... I have to gather my strengths first...
