Believe it or not, you already have the solution for both this problem and another one hiding after that.

  1. What Leo explained: your function getString is undefined, you need to reference it from its origin like so:
    var date = clickData.func.Dlg.getString("Enter date:");
  2. Bonus problem waiting for you: after the user-cancel check (if (!date) return which you already have), but before the for loop you need to convert the string date to an Opus' Date object, so you need this:
    date = DOpus.Create().Date(date); (otherwise the date.Format call you have below would fail).
