4.Next is the JavaScript part. Find

</body>

and replace it with 
 <!--Page Navigation Starts-->
<script type='text/javascript'>
var pageCount=6;
var displayPageNum=6;
var upPageWord ='Previous';
var downPageWord ='Next';
</script>
<script type='text/javascript'>

As you can see,there are some customizable parameters in this codevar pageCount=5;
This code determines the number of posts that would be displayed per page.var displayPageNum=5;
This code determines the number of additional page navigation numbers that will be displayed on the page.var upPageWord =&#39;Previous&#39;; var downPageWord =&#39;Next&#39;;
These two lines determine the text that would be shown for the previous page and next page respectively.
Label Fix
Now we have another problem.By default,the blogger label pages will  show 20 posts.We will have to cut this down to the value that we gave  for the variable pageCount (or the posts per page).For this we will have to edit our template
 
    

How to Edit the template to cut short the posts per page?
Go to the Edit HTML page and expand the Widget Templates
Now find each occurrence of
'data:label.url'
(including the quotes) and replace each of it with
'data:label.url + &quot;?&amp;max-results=5&quot;'
Here 5 is the number of posts to be displayed per page.
Now if you are using the label cloud widget by phydeaux3,then find
a.href = &#39;/search/label/&#39;+encodeURIComponent(t);
and replace it with





a.href = &#39;/search/label/&#39;+encodeURIComponent(t)+&#39;?&amp;max-results=5&#39;;
Here also 5 is the number of posts to be displayed per page.
Now you should have the Blogger Page Navigation working perfectly on your blog. 🙂
