What have you tried? How has it failed? What documentation have you read to help yourself out? We don't provide answers off the bat. We prefer that you show us what you've tried before asking for help. That way, we can address the issues you're having directly, rather than spoon-feeding you.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.

Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
