title: Crystal Reports - use formula for parameter alternative
body: <p>I have a report that shows some statistics for the previous day. Typically this is the previous day (dateadd("d", -1, CurrentDate)) but if it is Monday (dayOfWeek=2), I need it to use the previous three days (dateadd("d", -3, CurrentDate)) . I know how to do this, but I need these values to be defaults of the parameter, and be able to have the user be able to change this dates.  From what I can tell, you cant set the default value of a parameter to a variable. How else could I accomplish this??</p>
