According to google webmaster tool 159 urls has been submitted but why at sitemap page 159 url not shown? thebeautyonline(dot)com/sitemap.xml I select next page option too but nothing works
Do you have more than one page that is identical to another. Could dup;icate content be an issue here i.e your sitemap says the page has been submitted but Google is detecting more than a little similarity between pages?
