I have an author field which may contain up to 10 names. I'd like to create a new field based on the author field which will output like this:
If the author field contains more than 6 names, then output as first author., et al.
Grothe, B., et al.
If the author field contains 6 authors or less, then keep as is:
Grothe, B., Jacobs, G., Padgett, K., Aaronson, N. K., & Jacobs, G.
