this is the code so far.
It shows the last post (title+content) on top when you first open the page,
and it lists 5 titles from a specific category.
and “next” or “previous” at the bottom if there are more than 5 posts in the category.
Now, the problem is that,
let’s say there are ten posts, 1-10, one being the most recent post.
When you first go to the page,
it show the most recent post (title+content), post 1
plus just the titles of posts 1-5.
If you click on “next” to see the next 5 posts,
I want to show the last post (title+content) from the remaining five posts, post 6
plus the titles of posts 6-10.
What it does now when I click on next is
it shows post 1, or the last post viewed on top,
plus the titles of posts 6-10.
And when I click on let’s say post 7,
the lists of titles goes back to 1-5.

How can I make it so the list of posts changes only
when I click on next or previous.????
