How much should I be eating???

I am still trying to figure out what my individual daily calorie # should be. After reading other post that are similar to mine..I am confused because of the fact that people say they are sticking to the "1200" rule to lose weight and then others that say eat more to lose weight. I am 5'6...and are mostly sedetary because of my desk job. I do walk/run every morning for 30 mins. every day of the week. I'm not smart when it comes to this, which is probably why I am still overweight! Another thing is my weight has stayed the same for months now..it might go up a lb or two but then back down, up, down. Can someone shed some light for me please?
