Ash - 28 Oct 2006 22:02 GMT
I have a spreadhseet that has 50 rows (steps) and 12 columns. Th
columns represent groupings while the row are an assigned steps in th
pay schedule. The first column A  (monthly pay) is column B (annua
salary) divided by 12. The same is true for the rest of the column
like C and D, E and F, G and H and I and J. Recently I was given a tas
to raise salaries by a same factor for all employees. I did this usin
simple formulas and checked the result the long way by printing an
going through the whole record. My question is does any one know
formula to check for duplicate figures? obviously the same rate can no
be applied to two employees at different Steps and Columns

Assuming the values you need to check are in A1:A50, enter into B1 and copy
down to B50,
=IF(COUNTIF(A$1:A$50,A1)>1,"Duplicate","")
Then if you wish, sort columns A and B by column B. You could also look at
Conditional Formatting in Help to colour the duplicates red or whatever.
Obviously change the cell references to suit your needs,

Alan.

Alan - your formula is missing something. Also where do I put the
checked value? Since the spreadsheet is in continum A1:j50, i would
like to get a checked result some where out of this range.

Sorry, should be
=IF(COUNTIF(A$1:A$50,A1)>1,"Duplicate","")
You can enter this formula anywhere you want to and change the A$1:A$50 to
the column you want to check,
Regards,
Alan.

Alan - I know you are trying to help me and I really appreciate it. But
you gave me the same formula again. I am getting an error message every
way i tried. when I select the whole spreadsheet and put the formula
below data cells I get a circular ref error.

Ash and Alan,

This is what's happening.  I don't know what caused it though.

Both times Alan wrote this formula

=IF(COUNTIF(A$1:A$50,A1)>1,"Duplicate","")

which includes the greater than sign ">"  i.e. >1.

However, when Ash replied, the message quoted dropped the greater than sign.

It read:  Alan wrote .......

=IF(COUNTIF(A$1:A$50,A1)1,"Duplicate","")

See how the message dropped the greater than sign from the formula?

Ash, make sure you have >1 in the formula.  Try to type in the formula instead of copy/paste.  If your last column is J, try to use column k or l or m for the formula.

You said you had 12 columns.  So, I don't understand why you said earlier your last column would be J?  A to J = 10 columns.  I am lost.

Epinn,
I noticed that too, but only after I read Ash's second reply. When I read
the first one I just thought that I'd written the formula wrongly so I sent
the correct one a second time, thanks for pointing it out to me.
Ash,
You mention a circular reference, this is probably because you're entering
the formula in the range that it's searching. I can't really be specific on
your exact spreadsheet for obvious reasons, I'm just giving you a formula
that will highlight duplicates, you need to adapt yourself  to suit your
needs, if indeed it's suitable to you.
The formula =IF(COUNTIF(A$1:A$50,A1)>1,"Duplicate","") counts the number of
times that the exact contents of cell A1 occurs in the range A1:A50, if it
occurs more than once it will display "Duplicate", if not it will stay
blank. This needs to be in a cell out of the range it's searching otherwise
you will get the CR error message because it's searching a range that
includes itself.
Regards,
Alan.

Alan,  I don't understand Ash's need entirely.  One interpretation is that the columns A, C, E, G and I should be checked for duplicates simultaneously and not by individual column.  I know duplicates are not allowed in a column.  If a number exists in column A, can it also exist in column C?  Only Ash can tell.

I wonder why others don't join the party?  Usually this subject attracts quite a bit of attention.  May be we have too much of checking for duplicate numbers and counting unique values lately.

Ash, feel free to do a search.  There are quite a few thread on this subject recently.  Good info.

Neither do I. I would have thought that only one column would need to be

Many thanks to Alan and Eppin. The drop in the numbers/signs was very
confusing. I am working on teachers pay schedule. A teacher with BA
would fall on group one in which case the first column is monthly pay
while the second is annual salary. Each column represents some kind of
degree + credit hours. I do need to check all columns for duplicate
entry. Since I inherited a pay scale that does not have any meaning
(percentage wise) as to by how much each increase is I had to come up
with a somewhat complicated formula. Eppin sorry for the column count
mistake. I do have 12 columns. As to why there is no mass response, I
am as interested as you are to know why? Was this a simple question,
perhaps?

Hi Ash

It is unclear what you are trying to achieve.
What does each row represent, a different employee?
What does each column represent?
Can you provide more detail with a sample of a couple of rows of data,
and a further explanation of what you want to achieve.
Because of text wrapping with 12 columns worth of data, it will be
clearer if you post the sample in a transposed way, with columns going
down the screen, and rows going across the screen

Col,    Row 1           2        3
A,Monthly Salary,2000,2500
B,Annual Salary,24000,30000
C,BA Add'n,5%,6%
etc.

Ash,

The formula is correct. You need to enter these formula at the next
column not at the same column. That's why you are getting the circular
references. Copy and and paste the formula to all the columns till you
need to now the duplicate entries.

Hope that helps,

Thankyou,

Shail
