I have a worksheet *(sheeta) with a list of activities with "Open" and
"Closed" dates.

In worksheet B, I have A2:A50 I have
A B
1 =TODAY()-7 =COUNTIF('sheeta'!A1:A50,"=" &'sheetb'!A1)
2 =TODAY()-14 ={number of occurances between A2 and A1}
3 =TODAY()-21 ={number of occurances between A3 and A2}
4 etc....

In Colum B1, I do a COUNTIF('sheeta'!A1:A50,"=" &'sheetb'!A1)

In B2:B50, I want to do =COUNTIF('sheeta'!A1:A50,"=" &'sheetb'!A2 AND "<"
&'sheetb'!A1)

THe idea is to found out, by week (each day the start date will change to
TODAY()-7.)
Each day.

Any ideas?
