ah, ok
so, you set the price 1$ but still cannot fill the stadium.
1st - the tickets for asso games are in Friendlies Category , not League games (just to make it clear)
2nd - Building your lv stadium is not enough. It's good to finish also the relative lv parking facilities (not all your fans have SUV ) and maybe some more (club later).
3rd - If you have a google team to fill your group, you don't care about it's progress in the league and this team continually loosing, it's not attractive for the fans. maybe they won't come in your asso games either. 1$ for a league game maybe is attractive but not enough for a friendly.

If you want to discuss more. tell me your lv, the stadium seats and how many fans you had with 1$.
