Summoning more than one Olivia

I've tried summoning more than one Olivia in the Haunted Mansion "PQ" with my party, but so far I haven't got it to work. Both of my party members (supposedly) entered her name into the mirror at the same time, but only one Olivia managed to summon (and I think she was harder, too. :f6. In fact, we tried it twice in one PQ: first time, the window that said someone was coming popped up, but nothing happened. Second time, only one Olivia summoned.

Could anyone explain to me step-by-step how this is supposed to work?

Apparently you did it right o-o
It worked everytime for me. Tell your party a specific time to press ok?
Like at 59:40 on the timer or something.

I'm not really sure, seems like it was supposed to work for you but didn't.

For my party, we just stood there and waited to 59:00, and we all hit okay. It is probably just your timing, because we did it with 6 members and we never got more than 4 =[

You shouldn't enter at the same time.
Do it when you see the mirror cracking,if you enter in the same time,only one will be summoned.
If you enter some 0.*** seconds after it,it may summon more.
Actually,this is unfixable.
This kind of reactor is sided for the person.
If you enter it,and then press enter,some seconds before the reactor changes,it may still work for you.

They have to type Olivia with a cap O.

Well when me, Chuey, and another pal of mine try to do this we wait just a bit before summoning the next. We haven't failed yet.

They have to type Olivia with a cap O.

Hm, that might be the problem. Thanks for the info.

yea I found that most people aren't doing it "Olivia" but "olivia" instead. It is supposed to be with a capitol "O"

They would yell at me for doing it early or something, but then I realized they were just mistyping. lol
