[Pieces_of_SEVEN]

so I've already ordered from TA shop and had it shipped to my tenso address. but now I'm trying to order love classics and it won't let me. Having the same problem as before and foolishly can't remember what I did last time to get it to work. The only field that's not being accepted is the number field. it's like 4ts-4xxxxxx and I've been trying SOO many different combinations of things and it's getting on my nerves.

Having trouble remembering what I did last time...can anyone assist? Thanks :/
