To do that, simply write this calculation:
newResult =
Substitute ( originalResult ; "¶" ; ", " )

I'm using this function so that the user selects values (from within a portal) and i build a list from the selected. I then use the above function to add or remove this list from an existing list. I have found that if the user selects the last value in the portal, it doesn't work even though i have a valid list. I simply get a ? displayed.
