I finally got the multiple pages to work (thanks for the help, Meridian!), but I think that since only one item appears on the list of articles, a player will likely not know there is another page, as it requires clicking the "next" button, just as when going to the next item. Therefore I'm wondering if we could add a little indicator to show that the weapon has more clips.
Here is a mockup:
Considering that it's pointless to make multiple pages for a weapon with only one clip, I think there will always be a place for this indicator under the last clip.
