Ensure that the list of possible page positions corresponds to the number of pages that belong to each subject, not to the total number of pages in the table.
- [Instructor] So far in this chapter, we've learned…how we can nest our pages underneath our subjects.…In the last movie, we talked about how we can…more efficiently count the number of pages…that belong to each subject.…I now want to take those to two ideas…and combine them together to talk about how…we scope the page position by its subject.…You may or may not have noticed that we actually…have a problem in our current code.…If we go to one of our subjects, review the pages,…and then I click on one of the pages to edit it,…if I look at the position listing, you'll see that…I have 13 different positions available.…
Why is that?…Well, it's because I have 13 different pages.…But that doesn't seem quite right.…It seems like, instead, that I should have positions…one, two, three and four.…Right, that it should be scoped by the subject.…And then for another subject, such as over here…on Consumer, I ought to have positions one, two and three.…Right? I should never, ever run into a case…where I have position number 12 or 13.…
