Hello,
I got a list of about 3,450 rows of data. I need to figure out how many times a unique ID# show up two or more times in a column. For instance,


<table border="0" cellpadding="0" cellspacing="0" width="140"> <col style="width: 57pt;" width="76"> <col style="width: 48pt;" width="64"> <tbody><tr style="height: 14.4pt;" height="19"> <td class="xl65" style="height: 14.4pt; width: 57pt;" width="76" height="19">Date</td> <td class="xl65" style="border-left: medium none; width: 48pt;" width="64">ID #
</td> </tr> <tr><td style="vertical-align: top;">
</td><td style="vertical-align: top;">
</td></tr><tr style="height: 14.4pt;" height="19"> <td class="xl66" style="height: 14.4pt; border-top: medium none;" height="19">5/11/2011

How would I calculate the total count for each Unique ID.



For instance,



Total ID # 58 = only 2 total found
Total ID #81 = only 4 total found
Total ID #16 = only 1 total found
Total ID #45 = only 1 total found

to get unique id's you have to use advance filter

here is something a bit more dynamic, you can assign a name range instead of cell address b6 to b16 to make it even more dynamic.
