Getting data from another sheet using dates & description as criteria.

Hi

As my title says, i'd like using 3 criteria(start date,end date, description) in my second sheet to get data that match these criteria from another sheet.

I can do this using formulae, but as the range in first sheet will be big(5000-15000 rows), my pc will be too slow for all these calculations.

I'd like to use this in pc that use Excel 2003.

Any idea to do this using code?

Thanks in advance.
