Hi

You need to create 3 lists
List1 is the name of the companies , Dell, IBM etc.
Dell is Memory, Power Supply etc.
IBM is CPU, Board etc.

In the first validation cell, e.g. A1 set the validation to be List =List1
In the second validation cell set the validation to be List =INDIRECT(A1)

For more help on Validation take a look at

Hi

Im working with Excel 2007

I have 2 lists. In column A I have components and in column B I have
companies.

A B
Memory Dell
CPU IBM
Board IBM
Power Supply Dell

I have drop down list in F2 that contain the B column list (companies).

1. I want to create in F3 another drop down list that related to F2.
Example €“ if I choose Dell in F2, I want to see in F3 €˜memory & €˜Power
Supply option only
2. How can I avoid duplication in the F2 drop down list?
3. Do I need to use the LOOKUP functions?

Thanx
