Gaming 3375 - Know How (puzzle game)

[richard.brooksid]

I am on the 3rd level (Cave). At the entrance, you can either go left or right. I went both ways but am stuck on the right side, 4th puzzle from the start (2 before gold). I have spent a couple of hours on this one and lost some hair on it too. If anyone has some ideas or a way to solve I would be very grateful.

Thanks,
