In a school class modification tracking system, I have a global text field in a PopOver where the user can enter class number(s) that need attention. The user will click a "Submit" button on the PopOver to start a script that does all the work. Example, g_Text = "1,4,6 10-15". (Quotes are here for clarification.) I want to create a dynamic list that would contain "1¶4¶6¶10¶11¶12¶13¶14¶15" from the example. I hope the linefeed characters showed up in my example. I'm thinking that a custom function would be great here but I don't know exactly what to call what I need. Any help would be appreciated.
