Guild Wars 2

ok im in a guild that has just bought the guild armorer and i cant buy any guild armor. i dont understand this

Representing:
You must be representing the guild that has that upgrade trained up to access their armorer.

Guilds and Upgrades:
Guild upgrades are server specific. You must also have your home server for your account be the same server that the guild has the upgrade on to be able to access that guild upgrade.

So, if the guild trains that upgrade on the Eredon Terrace server, you must also have that server as the one your account is on and representing that guild to access that guild upgrade.

Are you sure you are on the same server that your guild has trained that upgrade on and that you are representing them?

Also, are you sure the Guild Armorer has finished training up and that it is not still in the process of being trained?
