Are these tickets good?

I have standing tickets #1476,1477 and 1478 on Wembley.
Does anyone know what this means? Are there 1400 people in front of me, or is it just a number? So that if I'm early, I can stand right behind the circle?
BTW, anyone else order from ticketline? They're ok, I hope?

They mean nothing, just be there early and you'll be fine.

i did for the wembley tickets as ticketmaster had sold out by the time i could book. i've ordered tickets for west end shows from them before and they were fine. don't worry yourself.
