I have converted my list-user field to text using the UserListToNames function. Now, I want to pull out the first three letters of each users' last name. So when I get the results "John Smith; Bob Jones; Robert Green" I want to convert that to "SMI, JON, GRE". The reason I want to do this is so that I can use the shortened description on a calendar report. The calendar report doesn't display even one full name, so I need to abbreviate to make it usable. I've seen some examples using Left,Right to trim characters, but not sure how to account for the fact that the field may only have one name sometimes and up to three names other times. Any suggestions?
