finding duplicates and deleting based on another column

[tpeter]

I have a spreadsheet of data that I have compiled from 6 different workbooks.
I have used a true false statement to identify the duplicated and now I need
to delete them based on which spreadsheet they came from. The consolidated
spreadsheet I have currently has 28,000 records, I am currently deletleting
them manually but this will take me until I am 100 to go thru. Any help on
this would be great.

In column A I have numbers:
56088769
57499354
60175071
60175071
60175071
5608437X
5608437X
5608437X

As you can see there could be 2 to 6 duplicate numbers. I need to find the
duplicates in column A, then evaluted column J to see where the source of
the data came from. The choices are:


Raw 02-06
PG &E Composite Data
PG&E Data 08

This is also the order of choice, if there are 4 duplicates and Raw 02-06 is
an option then delete the rest of the duplicates leaving only this one. If
there is a duplicate and raw isn't available then pick option 2 and so on.

Thank you for your help, it is greatly appreciated.

I have renamed the 3 criteria and sorted in assending order by column A and
secondary assending by column B. When I run the macro it says variable not
defined.
a b c d
e f
25123670 AC250 LIVERMORE 0.85 4/27/2004
25151368 AC250 BENICIA 0.62 6/7/2004
25168891 AC250 SAN FRANCISCO 0.05 12/23/2002
g h i j
k
8/17/2004 American Test 5-20-07 FALSE
3/29/2007 9/29/2004 American Test 5-20-07 FALSE
8/6/2003 American Test 5-20-07 FALSE

I have added numbers to the other 3 options and sorted it by column A and J
but still get varible is not defined on the macro stoping as soon as it
starts.

Thanks for all your help. I sorted by column A and J. I was not seleting
everything I wanted sorted so it was breaking. Went from 23,650 records to
12,303 when I ran by check for duplicates =countif(a:a,a1)>1 everything came
back false. Thanks again for all of your help it saved me a lot of sanity.
Another interesting note is I brought this file home to work on and I have
2007 and there is a remove duplicates button that gave the exact same results.
