GMAIL mail receive - Getting email body: Please select folder first. Use SelectInbox

[Bill Brower]

Does anyone know why I am receiving this error on a very basic script?
I am triggering an event on email receive using Gmail.

This is in the system log:
Getting email body: Please select folder first. Use SelectInbox(), ExamineInbox() or Select(String), Examine(String) method.

sub main()
dim index
dim subject
dim body
index = hs.MailTrigger
subject = hs.MailSubject(index)
body = hs.MailText(index)
hs.writelog "Email" , subject  & " --- " & body   
end sub 

Thank you!
