For Bug 2152 I've found I need to create a subroutine that checks whether a form element refers to a valid entry in the user's journal separately from the various subroutines for actually saving it as a sticky.

If a journal entry id can never be zero then this subroutine could return the id number if it is valid and 0 otherwise. In that case the subroutine can replace duplicate code in at least two places, but obviously if an entry can be 0 then the subroutine had better just return 0 or 1.
