Hi Amber,
This is fairly complex! It was fun though. Try this:
List(", ",
Left(NotLeft(Trim(Part(ToText(UserListToNames([User List],"LF")),1,";"))," ,"),1)&
Left(Trim(Part(ToText(UserListToNames([User List],"LF")),1,";")),1),
Left(NotLeft(Trim(Part(ToText(UserListToNames([User List],"LF")),2,";"))," ,"),1)&
Left(Trim(Part(ToText(UserListToNames([User List],"LF")),2,";")),1),
Left(NotLeft(Trim(Part(ToText(UserListToNames([User List],"LF")),3,";"))," ,"),1)&
Left(Trim(Part(ToText(UserListToNames([User List],"LF")),3,";")),1)
)
What you will want to do is consider how many possibilities you might have in your user list field. I have solved for 3 above. To add more possibilities, you would add another row like this:
Left(NotLeft(Trim(Part(ToText(UserListToNames([User List],"LF")),4,";"))," ,"),1)&
Left(Trim(Part(ToText(UserListToNames([User List],"LF")),4,";")),1)
With each row you add, you need to increase the first number by 1. See the bolded 4's above. Also note, each row would require a comma after it except for the very last one. (See the first two rows end with: )),1), and the last row ends with )),1)
Let me know if that works for you. Good luck!
