Please start over and carefully rewrite your question, stating exactly what you are trying to calculate. Take the trouble to use clear language. When you do so, I and others here will be glad to help if we can. If you have more general questions about how to tell Mathematica to produce what you want, please also state them clearly, so that some of us can help. For better or worse, learning how to use Mathematica is a significant job. Do as much studying as possible on your own, then if you are really stumped, ask for help with a specific difficulty.
