I'd like to include the first 20 characters of a variable in an alert email subject. I've tried substr($result.EX$,1,20) but that ends up including the static text "substr" as well as the entire variable value along with the parenthesis and 1,20.
Is the correct way to wrap it all in $ ? - $substr($result.EX$,1,20)$
What is the correct way to do this?
