In addition to my friend Mike's request, is your list within a table? If so, the column feature will not work. You need to move the list out of the table and then attempt to put it into columns.
For me, or other forum contributors to be able to help, we would need an editable copy of your sheet, containing representative test data - see: Tips for sharing.
