Try:
"Week of "+totext(dateadd("ww",{@weekofyear}-1,date(2005,01,01)-dayofweek(date(2005,01,01))+1),"MM/dd/yyyy") +" to "+
totext(dateadd("ww",{@weekofyear},date(2005,01,01)-dayofweek(date(2005,01,01))),"MM/dd/yyyy")
Substitute your WeekofYear for {@WeekofYear}. Please note that I believe the currentweek is week 24.
