How to cite page from section-page number style document? I've come across a problem during my bachelor thesis.

I'd like to cite a single page in a document, but it uses the "section-page" style of numbering pages of the document. It appear like I'm referencing pages 7 to 23, even it is just a single page. (I am using ISO 690)



What's the proper way to cite such page? Thank you.
You can write "page 7-23", so that the singular word "page" gives the reader a clue.  A range of pages would be "pages 7–23".

Alternatively, I would have no objection to "Section 7, page 23", though apparently JeffE wouldn't approve of that.
