Active User with user input
This query is the same as the one above however the static 60 days used above is replaced with a prompt.  At execution time a dialog will be displayed to enter the Activity Period.  In the query the static 60 has been replaced with {userinput:Activity Period (Days)} to prompt for the value.  This Subst is used a number of times in the query but only prompted for once, as the first response is cached and used for subsequent entries with the same label.  See Substitutions
