So your astore widget isn't working. This means you're not talking about HP's capsule. If you are, then your problem is that HP doesn't let you use astore. If you're talking about another site that you pasted the widget link into then....
There are only two (well three, but the third is unlikely) reasons to get that message:
1. You have no products in your astore. Check your astore.
2. You altered the html code given. If certain parts of the widgets are interfered with, the widget will not work.
3. Amazon and/or your browser are having issues.
