Where is Louis's suitcase on Nancy Drew: message in a haunted mansion?

Answer 1

I'm assuming you have the Game Boy Advance version of this game. If you don't, then I don't know what to tell you.

"The combination for the suitcase is on Louis' laptop on the Study Desk.

Start with the left-hand combination lock (click on the left-hand detailed
view). The numbers in the MIDDLE row of the combination dial are the ones that
need to read 4653. If you are successful you will hear the sound of a lock
popping and the view will turn to the right hand lock. Do the same as you did
for the other lock this time using the combination 4868. If you are successful
a lock will pop again and the briefcase will be opened. If you exit out you'll
have to redo the puzzle."

As far as the location of the briefcase goes, all I could find was that it's near the gaming table.
