Getting unexpected error messaage

I’m trying the following script, found elsewhere on this site:

tell application Mail¨
delete every message in junk mailbox
delay 6
delete every message in trash mailbox
¨end tell

All I get though is a message saying

"Error: Expected end of line but found unknown token.
Error Number: -2741
From Application: "

Can anyone advise me what’s wrong?

Many thanks, Richard

Don’t forget the double quotes


tell application "Mail"
