Help please - (booking) calendar


I have searched and found so helpful info, but I am still not there. I am newish to actionscript.

I am making a online booking app - I was using the dateChooser, which was great apart from I need to display the week numbers and I can’t seem to extend the class to do so.

Please help any suggestions or tutorials that will show me how to create a calendar with the same functionality as the DateChooser but also displaying weeks. There can be no backend/xml on this app (it sends the studio a email).
