Checking for duplicate entries
Hi
I have Excel 2002. I have a spreadsheet with a number of ingredients in the first column and the next 130 columns have formulations for various products made on the ingredients in the first column, these formulation all add to 100. Is there a way i can automatically check for any duplicate formulations? Thanks Daniel |

Insert a new column in B and add a formula of
=SUMPRODUCT((C12:EK12<"")/COUNTIF(C12:EK12,C12:EK12&""))=COUNTA(C12:EK12) -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "Daniel- Sydney" wrote in message ...

Yes, using conditional formatting.
Select all items in the row, say B2:EJ2 Goto CF< FormatConditional Formatting Change Condition1 to Formula Is Add =COUNTIF($B2:B2,B2)1 (note the use of $) Click Format Select Pattern Choose a highlighting colour OK This will highlight second and further instances of the duplicates. If you want all including the first, use a formula of =COUNTIF($B2:$EJ2,B2)1 -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "Daniel- Sydney" wrote in message ...
