Finding unique entries in a column
 

I have a range of cell entries,

Worksheets(Sheet1Name).Range(Cells(Sheet1FirstRowN um, _
Sheet1RespCodeColPointer) & ":" & Cells(Sheet1LastRowNum, _
Sheet1RespCodeColPointer))

in which I need to:

1) count the number of unique entries and store the result in a variable

2) copy each of the unique entries that were found to an array, and then
refer to each entry in the array in a subsequent formula

Any help in showing me how to perform these 2 steps would be greatly
appreciated. Thanks.

Hello,

I suggest to use my UDF lfreq:

John Walkenbach shows how to loop through a range to get the unique values he
http://j-walk.com/ss/excel/tips/tip47.htm

And once you do that, you can use yourcollection.count (nodupes.count is what
John used) as the number of unique entries.

Finding unique entries in a column
 

You don't need VBA to perform this task

If your numbers arre in column A starting in row 1, then put 1 in cell B1.
the first number is always unique. In cell B2 put in the following formula
=IF(COUNTIF(A$1:A1,A2)=0,1,0)
Notice the $1.
Copy this formula to other cells in column B. The values in column B witth
a 1 is the unique numbers. You can SUM column b to get the number of unique
numbers.

I can show you how to do this in VBA if you don't want to do it in a
spreadsheet formula.

Joel,

Thanks for your suggestion, but I really need to perform the task in VBA
using the range:

Worksheets(Sheet1Name).Range(Cells(Sheet1FirstRowN um, _
Sheet1RespCodeColPointer) & ":" & Cells(Sheet1LastRowNum, _
Sheet1RespCodeColPointer))

Thanks again,
Bob
