I will be helping you with your question today.If you could please attach the code that you have so far - either by using the paperclip icon here, or by uploading it to a site to which I can have access, like WikiSend or OneDrive, then provide me a link, that would be helpful so I could take a look at what you already have. Then I can take a look at it and let you know what I think.Mike
