No so basically when you're assigning the ticket to the person aged 18-25 must fit in the age category which is set by the home club - this varies game by game. So for this someone who is 22 years old on city's database would be in the adult category, but for other games like southampton I think the age bracket was young adult and it was £27 for an 18-25 ticket.
This morning though I believe there was an error in the system as I refreshed bang on 9 and assigned tickets as I normally do, but I got an error message saying 'the quantity of tickets owned by ... has exceeded limitations' as if I had already purchased one, which was wrong.
Was hoping to do 38/38 this season but looks like this could be the one to let me down unfortunately.
