Multiple Criteria for If statement in AppleScript

Question

I'm attempting to modify an applescript that fires a growl notification when there is a new message in Outlook. The original script is here.

In my if statement, I am trying to say that if the folder is either Deleted Items, Junk E-mail or Sent Items, don't fire the notification.

Here is the statement:

if folder of theMsg is "Junk E-mail" or "Deleted Items" or "Sent Items" then
    set notify to false
else
    set notify to true
end if

It appear that applescript does not like the multiple is/or items I've added. Is there a way to include the multiple criteria, or do I need to write a nested if/then?

The correct way to chain if conditions in AppleScript is to repeat the full conditional:

if folder of theMsg is "A" or folder of theMsg is "B" or folder of theMsg is "C" then

– there is no implicit repetition of the left hand argument. A more elegant way to do this is to compare your left hand argument to a list of items:

if folder of theMsg is in {"A", "B", "C"} then

which has the same effect (note this relies on the implicit coercion of text to list, which, depending on your tell context, may fail. In that case, explicitly coerce your left, i.e. (folder of theMsg as list)).
