Under Data Validation, look for 'DV0005 - Data Validation "Columns"'
> I would like to have a drop down pick list that returns the value from
> an adjacent cell instead of the one picked. For example, I have a list
[quoted text clipped - 5 lines]
> description in column B to pick from but return the abbreviation from
> column A. Can not figure it out, what am I missing?
