Report label caption expression

I want the header on a report to display the year from a variable along with some text. When I set the value to "str(m.Year) + 'Auto Mileage Report'" that string is displayed rather than "2015 Auto Mileage Report."

I think I solved this years ago with the use of a special character or syntax but I can't remember what it was.

Thanks in advance for any help,

Joe
