Excel 2010 :: Filtering Dates And Counting Occurrences?

I am using Excel 2010, and trying to count the number of times a certain name occurs within a specified date period. The date range start date is manually entered in F7, and the date range end date is manually entered in F8. I need to be able to choose different reporting periods. The answer to this question goes into F3.

I also want to know how many working days (Column D) it takes per name. A working day is Monday-Friday, less public holidays. In this period there have been public holidays from 24 December until 2 January (inclusive), 20 January, 6 February, 18 April, 21 April, and 25 April. I put these dates manually into the worksheet "Holidays".

For the number of times a certain name occurs I tried the COUNTIFS function but keep getting a "zero" value. I used the NETWORKINGDAYS function for the working days and have incorporated the holiday periods. That seems to work OK and I can live with the negative date values showing here.

The really tricky part for me - can I combine the COUNTIFS (assuming it works) and NETWORKINGDAYS functions into a single function to only count the working days of a specific name. As some names have yet to be completed (i.e. there is no data in Column C) how do I not count those? The answer to this question goes into F4.

There will be about 6 of these spreadsheets, and I intend to link all worksheet data into a "master" spreadsheet which automatically updates whenever it is opened. The separate spreadsheets are stored in a document management system rather than a network drive so I can't state a filepath.
