I am not able to put stuff in the circle at the giant's grave! I do not know what I missed!Any suggestions?I have the sword.I also have the dirt,holy water,anselm,and mouse.
Have you checked out the walkthrough here? If you look carefully at that, you might be able to figure out what you missed.
If someone who has played the game is not able to offer assistance, my advice would be to check out a video walkthrough on YouTube, if all else fails. I could help you find one, if necessary.
