help!! - examining room / mixture machine

[Maroth]

NeroAngelos: Brilliant, thats the one.

I read that part of the note probably about 10 times, but I thought the order was applying to in your inventory or where you found them in the room. It just never clicked exactly what it meant.

Thanks very much!

Nah, I still can't figure it out...

Could sb please tell me in which order I have to activate the buttons?

Edit: Nevermind, got it...
