The operator is fine.
The error you should have encountered was something to the effect of
using a reserved word for a variable name. "fileName" is a property of
media container objects like players and images, used to reference
externally-stored media files. It's also a property of a mainStack,
referring to the file it's associated with.
As with more formal languages, a little Hungarian notation goes a long
way, not only in making the nature of variables more distinct but also
in avoiding conflicts with reserved words:
