thanks Trevor
this works but it doesnt quite do what i need,assuming the dates are in
A1:A1000, i also have in Column B the week commencing dates from the start of
the contract which in this case is 5/6/06 then 12/6/06 then 19/6/06 and so
on, can your formula be made to work so as it will calculate how many times
the dates in A1:A1000 occur between the week commencing dates in Column B?

Sorry to be a pain

is
a formula to show how many times the task has beem completed in a week.
for
example if the column had the date 12/6/6 three times and the date 15/6/6,
seven times then between 12/6/6 & 18/6/6 the task has been completed ten
times.

is this possible, any ideas?
