Hi,

I can recommend that you copy all the columns to a single excle sheet.
This
is basicall to run an advance query which will fetch you all the
information
for you to compare. I shall explain you how to do it.

Assuming that you have copied all the columns to a single spread sheet,
you
know the column heading now, save the excel sheet.

Now I wiil be using the Advance filtering techniques so that all the
column
information are retrieved even if the typed cells are misspelled, which
normally is not the case when you do a simple filtering technique. The
filtered values may not be correct.

To retieve the values;

1. Select all records and the column headings and define a name for the
range List. This is the List range name.
2. Select all column headings and paste in a seperate row anywhere in the
spreadsheet.
2. Select the pasted column heading along with an empty row and define a
name. This is the criteria range name.
3. Define a criteria on the second row for all columns, if necessary. For
example S* will display all details specific to "S'.
4. Click Data- Filter- Advanced Filter
5. Type the List name
6. Type the Criteria Name
7. Click copy to another location option - Mandatory
8. Click Copy to
9. Click the cell below the criteria range

All data will be displayed specific to the query you requested. This is
very
usefull if the spreadsheet data are mistyped or mis-spelled. Now you have
done a database funtion on your excle spread sheet.

Does anyone have any idea on how to determine the values under following
conditions?
Given a list of numbers sorted by ascending order from top to bottom
under
column A, I would like to determine the minimum difference on the range
within this list covering 50% of total numbers, and return the smallest
number within the range in cell B1 and the largest number within the
range in
cell B2.
Does anyone have any suggestions?
Thank you in advance
