Hi, I'm having some trouble with decrypting this ciphertext problem here:

j r g d g i d x g q a n n g z g t g t t s i t g j r

a n m n o e d d i o m n w j r a j v k s e x j m d x

k m n w j r g m t t g d t g o g n j a j m z g o v g

k i n l a q g t j a m n x m s m j j r g k o j t g n

w j r g n j r g v a t t m g t a w a m n o j j r g w

i z g t n s g n j i b a b g u

I tried to solve it, but it just ended up with another unreadable result. I am new to decrypting and any pointers as to how I could determine what kind of cipher it is and how I could solve it would be great. Thank you for your time.
