I've got an expression that doesn't always return the same value. Most times, it returns result number 1 inside " " marks. However if there's no result, it returns the word null but with no " " marks around it. As I don't want to display the " " marks, my expression parses them out. However if the result is null, it breaks the whole expression...
Thanks. I ended up grabbing the whole field (either null or "title") and then substituting the word null, or the " character to remove them. Worked nicely in the end.
