My understanding of Workbook_SheetChange is that with ANY change ANYWHERE in
the workbook, the code runs, correct? I can't get it to work and don't know
why:

GOAL: Resort the "PatientNamesRooms" (just a list of about 60 names and
associated hospital room numbers) whenever a change is made on a different
tab within the workbook. Cells in "PatientNamesRooms" are index formulas
that get names based on room numbers from a main roster of names. We need to
quickly find the name alphabetically to determine what room they're in.

I've gotten the code to run (names to sort) using Worksheet SelectionChange.
But that doesn't meet my need. It needs to resort anytime someone updates a
name in the roster (like when a patient leaves or is admitted on the floor).

CODE THAT WON'T RUN:
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Source As Range)
Range("PatientNamesRooms").Select Selection.Sort Key1:=Range("A1"),
Order1:=xlAscending, Header:=xlGuess, _
OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom,
DataOption1:=xlSortNormal

End Sub

Help?
