How to count values separated by commas

A field in a portal displays all the names of the authors of a document, those names being separated by a comma. I want to apply conditional formatting to that portal field so that when there are more than two names in it, they get displayed in font 12 rather than font 16.


My question is: how do I count values separated by a comma in that field?


Thanks for your help.
