Lookup On 2 Axis

I have a table as attached. What I have is 2 tabs. Data - is the raw data which shows the date and time of each application per person and the time cut and formatted for lookups. Sheet 1 - This is a rota showing each member of staff.
Below the rota is a definition of each shift, i.e E = Early which is 8.30 to 5.00pm.

1.
At the bottom of sheet 1, I would like the total of each application for each member of staff for the time they have worked for each day.

i.e if staff member N-R worked a late (L) on the 2nd, I would like the number of application taken on the 2nd for N-R between the hours of 10.30am and 19.00.

I have tried nesting a vlookup and a hlookup function but I just cannot fathom it out. I have also tried to use coutifs().

OR

2.
On the data sheet I would like an additional column after the cut time to flag up applications taken for each member of staff during their shift. i.e if N-R takes 5 application on 22/12/2010 between 8.30 and 12.30, 3 after 10.30. I would like each individual app to flag up in its row if taken after 10.30 for this member of staff on this day.
