Unfortunately, the most important part of the screen shot is not visible at all. Why not just paste the query you have used here? One piece of unasked advice. Please do not all of your data access code under the button click event. Not a very good practice. I suggest you create separate classes such as SiteUser, DataAccess, etc. Remember Abstraction is the key.
