Using ranges to populate a portal

[etsmarines]

I have a donation table with over 22000 different donations. I also have a contacts table that has all the contacts corresponding to the donations. I have another table that i want to use for donation searching. For example I would want to search for all donations between two dates and between two amounts. I know how to set up a range field that auto calculates two fields and sets it up as a range so if i put 1 in the low amnount field and 30 in the high amount field the amount range field auto calculates to be 1...30. How can i set up a portal in the field to show all the donations that match the dates and amounts criteria i enter into the fields. So if for example I enter 1/1/2000 in the start date field and 1/1/2010 in the end date field and 1.00 in the low amount field and 200.00 in the high amount field the portal would show all donations that are between 1/1/2000 and 1/1/2010 between 1 dollar and 200 dollars.

Thanks For The Help!
