Option Tag with related database

[Go Ducks]

I seem to recall doing it, however, I can't seem to remember how ( I can hear the snickers now).

I have a value list in a database that is from a related file in another (ie. Value List Name = Name,

Source = From Relationship, Values = Field: "Database::Field Name"

I can't remember how to write the FMP-Option values to access this Value List.

Thanks in advance.
