How to use the offset Function (Part IV)


October 19th, 2005 by admin admin

From part III, you have learnt how to draw a dynamic Excel Chart. In this part, you will learn how to create a dynamic validation list using the same formula.

For those who don’t know about data validation, it’s purpose is to limit the type of data users could enter into a cell. If a data validation is a list, it will only allow users to select from the list.

Copy the formula “=OFFSET(A1,0,0,COUNTA($A$1:$A$100),1)” into the list as shown below. Click “OK” and you are done. Now, when you add or delete the listing in column A, the data validation list will get updated automatically.
