I have combined several fields (Surname, First Name, Cell, email) into one field in a database. I take the associated Company Name from a different database file and incorporate it into this 'composite' field giving me (Company, Surname, First Name, Cell, email), works fine. I want to use this composite field in another database file as a drop down menu (and use lookups to fill in the fields in this file). However I cannot do this because when I try to setup the drop down menu referred to above I get the message "This Value list will not work because the field.......cannot be indexed. Proceed anyway?".

Any help would be appreciated, Thanks. Heraldo

You can not use it this way since you are referencing a related field. Since it is being referenced, it is unstored and can not be indexed. Furthermore, since it not indexed, it can not be used in the value list.
