Put yourself in our position: we don't know you, we don't know what you are working on, we don't see your data; all we have is our knowledge of Stata and what you tell us about your problem. Given that, read your question again, and imagine how we could possibly help you based on the information you gave us.

In the FAQ (on this page at the top black bar there is a link to the FAQ) there is a lot of information on how to ask answerable questions. Please read that, and ask the question again in a way that we can help you. Particularly (but definitely not exclusively) look at the section on giving us example data.
