Hi

I’m 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
