Missing info. on ticket

Received a speeding ticket in Illinois.
I paid cash for my bond.
No court appearance required.
Question is.....I did not sign the ticket nor is there a complaint case number listed or anything in the box DCN. Are these important things that should have been filled out? Will this be something that I may be able to get off on due to an error on the officers part? If not I will just plead guilty and get court supervision but was wondering, (they already have my money anyhow) but maybe I could get it back.
Thanks,
Will
