extracting a range of data between two date

[newton.rogers]

Details,
Column A: "In Dates" in the format dd/mm/yyyy
Column B: "Out Dates" in the same format
Column C: Calculates elapsed working days i.e using function NETWORKDAYS
All colums can have up to a years data which sometimes have a number of "In Dates" which have the same date and the same for the "Out Dates" i.e. the same dates make occur more than once.
The spreadsheet is used to keep track on a number documents coming in, being processed and then being sent out. We use this data to check numerous bits of information, how many documents we received, how long we took to process them and variuos other calculations such as average processing time, max & min processing time etc.
What I am trying to do is to be able to extract the data from column C for a certain period ie from a start date to an end date and then do the necessay calculations on the data extraced. Thanks - "Stumped

my email address is newton.rogers@sky.com. The version of excel is 2003 and this is what I require. The blue figures are the dates that are input, the red figures are the result. The other figures are the data that is already in the spreadsheet. Thanks in advance.
