    1. CO`SELECT COUNT(StoryId) FROM Likes Where StoryId=1001;` - so according to this query the number of rows represent the number of likes?

    2. COIf you are using `<% %>` to assign a value to a `lable` or some display control, then it should be inside `''`. I saw you are using it in `""` (`Text="<%#Bind('StoryId')%>"`). change this to `Text='<%#Bind('StoryId')%>'` then it will work.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
