Recruit more than one friend

Theoretically you can recruit more than one friend, but when I access this page:

https://na.finalfantasyxiv.com/lodes...riend_recruit/

And I give the button it redirects me to the mog station and does not allow me to redeem any code. It is normal?

From the Mog Station they give me a friend code but no place to exchange any code

you give out your code to others, then they purchase subs. you don't do any entering of codes if you're the one giving out the referrals.

EDIT: Okay, I get it, thanks.
