In your table that is serving as the source of values for this list, define this calculation field:
List ( YourCurrentValueField ; "Other" ; "None of the Above" )
Define your value list to list values from this calculation field instead of YourCurrentValueField and you'll see all the current values in this field, plus the additional values specified in this List function in the calculation field.
Thank you very much! That makes sense. I didn't know about the List() function before.
Is it possible to apply this principle somehow in cases in which the original value list was drawing from two fields, showing values from the second field but using values from the first, using only related values? To put that another way, in cases where a value list is showing, e.g., a Name, but actually entering an ID number (these are two fields in the same table), and only displaying values related to the current record, is it possible to apply what you explained to me to add several values (e.g., "Other" and "None of the Above") for all records, as these two values won't be related to the current record?
Thank you! I appreciate your help.
Because these values are in every single record in the value table, they will appear in all conditional value list subsets.
Try it out and see how it works.
