I am looking for a function that can fill in the empty cells below. So, if
number 1 then the lowest overall start date and the overall last end date.
Can anyone provide
me with a function that does exactly this?

Overall Description Overall start Overall end
1 Communicationplan ? ?
2 Site As/IS ? ?
3 Projectplan ? ?

Hi Chris,

If I understand correctly couldn't the VLOOKUP() function solve your
problem ?

Chris,

Try these: both entered as array formulae with Ctrl+Shift+Enter and copy down.

In the formula below, I had the "output" table data starting in row 14, so
A14=1, A15=2 etc.

For overall start ...

=MIN(IF($A$2:$A$10=$A14,$D$2:$D$10))

For overall end .....

=MAX(IF($A$2:$A$10=$A14,$E$2:$E$10))

Output table ....

Description Overall start Overall end <==row 13
1 Communicationplan 01/01/2006 01/06/2006
2 Site As/IS 01/02/2006 01/01/2007
3 Projectplan 01/02/2006 01/01/2007

You will probably have this on a separate sheet, so qualify the ranges.

For example output table in on Sheet2 , with data starting in row 2 so
formula in Sheet2 would be:

=MIN(IF(Sheet1!$A$2:$A$10=$A2,Sheet1!$D$2:$D$10))
