duplicate rows

[Gary Reger]

i have a worksheet that has

Client Task Description Hours Month Day Year Name
soandso payroll type of p/r 1.00 jan 1
2005 me
whats bookkeeping type of bkpg 2.00 febuary 4
2006 him

i have in a list. there are almost 2000 rows. Would like to be able to find
duplicates by comparing hours and months and year an name then highlight the
duplicates.

I get the list by coping and pasting values from timesheets to a worksheet
named all time data. i am looking for a way to make sure that the
information I enter is correct and not duplicates.

Thanks for any thoughts
