Change date order for comments field

[RS Kate]

I have modified a form for using inventory. In the subform there is a comments field with the following: =ColumnHistory([RecordSource],"Comments","[ID]=" & Nz([ID],0))

Now, the history is working fine, but it puts the most recent update after earlier updates (in other words the oldest update is displayed at the top). How do I reverse the date/time order to show the most recent update (descending order)?

Thanks in advance!
