didn't understand what is the error

Why is this showing error

src/code.my.com/git/files/files.go 
package files

import ("os"
"fmt")

func Size(fileName string) (int64, error) {
  fileInfo, err := os.Stat(fileName)
  if err != nil {
    // RETURN THE VALUES 0 AND err
    return fmt.Println(err)
  }
  // RETURN THE VALUES fileInfo.Size() AND nil
  return fmt.Println(fileInfo.Size())
}

Some hints:

  • You won't need to import fmt or use fmt.Println since you won't be printing anything
  • You are to return two values. Separate them with a comma. See video
  • If err is not nil return 0 and err
  • If err is nil return fileInfo.Size() and nil
