I'm a bit stuck - hoping there is a workaround that someone might know of. Unless I'm missing something obvious, which is also likely!

My FIRST Occurrence field order in a Citation, sees all the authors being listed.
The SUBSEQUENT occurrences, must display "et al" where >2 authors exist.
Whereas I appear to be able to edit the "et al" in the line below CASE in the Format Manager - this presumably only effects the FIRST occurrence.
When it comes to the SUBSEQUENT occurrence, 'et al' is controlled by the drop down selector, and does NOT allow editing.
My format requirement is for 'et al' without the subsequent .[period] after 'al', as in "Botha, Greef et al"...
Any suggestions?
