Sorry if this has been covered before, but is there a way to sort the sort list? They seem to be listed in relation to when the fields were added to the db. I wrongly assumed the 'Display Column' would do this (not entirely sure what this does do as I've numbered them all but nothing makes a difference!)
The help section reads:
Sortable means the list presented on the "List Participants" page can be sorted by this field. Of course, it must have a non-zero value in "Column" to be seen at all.
Can you expand on this please?
