calendar pop up for my solution

[meancode]

hey all,

i am using (well trying to) the calendar file off of the Everything CD, there is a similar one on databasepros.com. has monday 1, monday 2, monday 3 etc. for the dates. well im at a loss for getting the actual day when a user clicks on one of those squares (monday 1, monday 2, monday 3) etc. its pretty easy to grab the year, and the month, but how to i capture the actual day a person clicks on?? thanks.
