Not sure, Chuck. Looking at a walkthrough, there is a scorpion seal which is extraneous and you do not use it to solve the puzzle. The correct seals should be placed in the following order from the top down: Jackal, Ibis, Arched figure, Children. Is this how you have placed the seals?
If you have placed them correctly, then it's possible (although I haven't played this game) that there is something else you need to have done/looked at, before the game will recognize that you have the correct solution.
If all else fails, you could look at a walkthrough on YouTube.
