I tried doing this to get unique numeric entries out of a column but it
didn't work:

- Select the column to filter.
- From the Data menu, choose Filter, Advanced Filter.
- Choose 'Copy to another location'.
- Leave the Criteria Range blank.
- Click the little box to the right on the "Copy to:" part and select
the copy to column in Excel.
- Click the same little box to get back to the filter.
- Add a check mark to the Unique records only box.
- Click OK.

Here are the entries I'd like to sort:
200.00
1001.00
1222.00
1001.00
2544.00
2154878.00
1222.00
6555.00

Here's what I get
1001.00
1222.00
1001.00
2544.00
2154878.00
6555.00

You can see 1001 is repeated. Any suggestions as to why this happens?

Thanks,
brett
