Dream Chronicles, level 15, forest level, please help!?

Okay, so, in the 15th level, after putting the lamp together- you have those two puzzles to complete. I have completed the left side one, it chimed and lit up blue. I have the right side puzzle put together, the right way, or at least i think so. ((top row= rounded, empty, rounded. middle row= half oval, rounded, half oval. bottom row=L shaped, door type, L shaped)) but it doesn't chime or light up and I'm stuck. Please do not post links as your answer, as I have already searched for it and found a few different sites, none really help though. Have saw this question on a few of those pages, none really answered. Thank you in advance. (o:
