Hi leobebert. This is really basic. When you seek help on a technical forum, it's useless and annoying to those that could help you, to say only "this doesn't work" or "I can't do that".

Give the information that will allow any willing helpers to diagnose your problem. Specifically: What tool(s) are you using, what documentation have you read, what code have you tried, what result do you get? This means, show your actual attempt and your actual results. No more vague questions!
