```There was also a similar thread under Excel Worksheet functions titled
"Delete duplicates".

Solution provided was to use:
Data>Filter>Advanced filter>Copy to another location and unique records
only.

Once u get ur unique numbers in a separate table u can then use
COUNTIF(range,criteria) to count the occurence of each unique number in
the original list.

Cheers.

```To identify the number of dupes, say in A1:A1000 then use this formula in
another column  (Say E2 and copy down)

=COUNTIF(\$A\$1:\$A\$1000,A1)

Other ways of handling dupes can be found here

```Hi!

Assume your list is in the range A1:A100

Count of uniques:

=SUMPRODUCT((A1:A100<>"")/COUNTIF(A1:A100,A1:A100&""))

>I would also like to know the number of times each value appears in the
>column.

One way to do this:

Use Data>Advanced Filter to copy unique values to another location. Assume
that new location is B1:B10. In C1 enter this formula and copy down to C10:

=COUNTIF(A\$1:A\$100,B1)

Hello, I have two tables. One stores "employee information" and another stores "time sheet information" for all the employees.

getting more columns and data onto one page in Crystal
Hello: Since you can only place so much data onto a "piece of paper", likely the answer is "no". But, even after choosing "Landscape" in Crytal (10.0), there's not a way of getting as many columns of data onto a report as I want--is there? Ideally, I'd like to get 14 columns on there but am running out of room on the right. Also, I have placed a cross-tab on my report that prints on multiple pages instead of just one. Of course, since the cross-tab has 83 rows of data, my guess is that there is nothing that I can do about this either. Is there? ...
