[AccessD] Figuring the date

Hey Everyone,

I have two pieces of information - the year and the week # within the
year, for instance 2008 13 is the 13th week in 2008.  I have questions
out to the client about how they define the week (Sun-Sat, Mon-Sun) and
how the first week of the year is defined - week that January 1 falls in
or first full week of the year.  Anyway - what I need to do is create a
function, unless one already exists, when fed these two pieces of
information returns the Monday date (short date format) for that week.  

Any help is appreciated.
