@dblookup and [RETURNDOCUMENTUNIQUEID]

What is the syntax to get this to work? The help file is not clear - it indicates that entering [RETURNDOCUMENTUNIQUEID] as the last item forces the lookup to return the unique ID and yet you still have to put a column no or field name in the @dblookup. Ideally I want to put a doc link into a rich text field depending on a key value being entered into another field.

either put “” or 0 in for the column no as a place holder.

Thanks Stan.

Also for the unwary I discovered that ‘concatenating the keywords’ means put colons between them.
