@MichaelBurr: I am rather positive he just needed the additional pair of quotations; the /s was redundant In cases like this, because the ailments below which /s makes a variance weren't satisfied.

The width isn't specified in the structure string, but as yet another integer value argument preceding the argument that should be formatted.

influence of /S is usually to override this a person exception, so the two quotation characters are still eliminated in that circumstance.
