I have a project log that has project names, dates it was worked on,
hours projects are worked on.
eg.
3/1/2008,project a,task 1,2 hours
3/1/2008,project b,task 2,3 hours
....
4/7/2008,project a,task 1,3 hours
....

I'd like to find the dates project a is worked on so to put the
beginning and ending of project a. If it's not possible, it would be
nice to show only project a and hide all others so I can find the info
visually.

Thanks for any advice.

Try these...

Dates in column A
Project name in column B

Earliest date for project A (start of project):

=INDEX(A1:A100,MATCH("project A",B1:B100,0))

Latest date for project A (end of project A) array formula** :

=MAX(IF(B1:B100="project A",A1:A100))

Format as DATE

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Thanks for the help, Biff.
The first part (start date) works, but second one I got #VALUE!
error.

Don't forget to use ctrl-shift-enter like Biff explained!

This great. Thanks for the hint. The only drawback is that I can't
copy and paste to multiple cells like other calculations.

sorry, copy and paste works. I manually entered some data before
reading the answers. The text didn't change after I pasted the
calculation so I thought it wasn't pasted over. With closer look at
each cell, I found they were replaced witht the formula. No control-
shift-enter needed.

Thanks for the helpful newsgroup!!
