Yeah, I know, you press the arrow to the side, and use the fountains (according to my instructions) If you really just cant figure it out I can give you the password?
With the fountains? You're going to try to make the symbols (pi + circle + square) and then that combo of symbols will make a letter, the 5th letter is V (I got stuck on that one), remember to keep them in the symbol order, and then use any of the corresponding letters on the big stones.
