Hi, Try following steps in excel Range a2 1 go to data then data validation 2 settings 3 allow custom 4 formula =countif($a$1:a1,a2)=o 5 copy this cell and paste down with validation
This will not allow you to reenter name if you use formula =countif($a$1:a1,a2)<>0 in conditional formatting then it will highlight when ever their is duplicate entry Thanks and Regards, Somnath C Pardeshi Sent from BlackBerry® on Airtel -----Original Message----- From: rajeyssh aggarwaal <rajey...@gmail.com> Sender: excel-macros@googlegroups.com Date: Fri, 10 Feb 2012 12:30:16 To: <excel-macros@googlegroups.com> Reply-To: excel-macros@googlegroups.com Subject: $$Excel-Macros$$ alert for duplicate name or number while entering the data in the sheet Hello Sir, Is it possible while we entering the date in the sheet system alert us that the name or number or text already in the sheet but not limit the entry of the data, if yes let me know how can we do it and is it possible to imply the rule in few rows not in all the rows. thanks & regards rajesh -- FORUM RULES (986+ members already BANNED for violation) 1) Use concise, accurate thread titles.
