Code cracker

[cherrycherry]

Hi, I have posted a question about cracking codes in How It Works, but after looking at the other questions in that section, I think I've made a mistake and should have posted in here instead.
The code I have to solve is from these letters:
BGMFRRRMAYJNIEPOOENAOUUY
Any help would be very much appreciated as we have been trying for a long time to solve it. Thank you

Put the letters into a 6 x 4 grid and read the columns down the way starting on the left.

B G M F R R
R M A Y J N
I E P O O E
N A O U U Y
