Please Help! World 7, Level 4 - The Humans

I'm really stuck this time playing The Humans.Can anyone help?I cannot figure out how to complete World 7, Level 4.I end up with the 2 cavemen, the rope and the torch. I also end up with no way to complete the level.I also cannot figure out how to press the 2 switches, where the triceratops was.Any help would be appreciated.Thanks in advance.

I guess nobody plays this game. Which is a shame. I really enjoy it. I'm now on the last World (number 8), Level 3. I wish there were more games like this one for the DS. I like it so much that I even got the PC version.I finally beat World 7, Level 4. I figured out what I had to do. I forgot that the Witch Doctor counts as a human, not just the cave men.

I've never heard of this game.
Maybe that's why no one plays it.
