display values between two dates
 

I have a workbook where i can select a start week# based on week 1 thru 52,
which will display 12 weeks of data from selected start week, using lookup. I
wish to expand on this further by selecting a start week and an end week,with
data displayed between the two, it could be only two weeks or twenty weeks.
To lookup the start and end weeks is fine, i am however stuck on displaying
the inbetween, any help will be thankfull.
