Scrape page content and traverse site by clicking older pages link

The site is a blog site with pages and an older link at the end of the page. I'm trying to get the content of all the pages.
The url and sitemap is below. Its traversing all pages but scraping only the first and last

Url: http://arnabchoudhuri.blogspot.com/

Sitemap:
{"_id":"test","startUrl":["http://arnabchoudhuri.blogspot.com/"],"selectors":[{"id":"main","type":"SelectorText","parentSelectors":["_root"],"selector":"div.main","multiple":false,"regex":"","delay":0},{"id":"older","type":"SelectorLink","parentSelectors":["_root","older"],"selector":"a.blog-pager-older-link","multiple":false,"delay":0},{"id":"old main","type":"SelectorText","parentSelectors":["older"],"selector":"div.main","multiple":false,"regex":"","delay":0}]}

All help is sincerely appreciated

Thanks

You only need to make main a child of older (it should be under both _root and older) and it should work.
