Oh, are you from the chapter at Morehead State? We went there several years ago for Region Day.
You would have to be an initiated member to know the answer to your question. If you are initiated but still don't know (and trust me, I can understand because I had been active for months before I understood what the letters meant 'cause it's all really hard to absorb), talk to your chapter advisor or one of the officers. I'm sure one of them can clear things up!
