I am attempting to create a web page where users will enter tasks for 
specific days.  I want to have a button which will popup a small calendar 
(within the page, not in another window) where they can click a date and 
that date will then fill into a text box.  Has anyone seen anything like 
this and does anyone know how to perform this functionality?  I have been 
searching the web for a while and haven't been able to find anything 
remotely similar to this.

Thank you in advance,
Chris
