    3. COI can only assume that the $data array was used somewhere else and is somehow in scope when you attempt to set the values manually setting the numeric indexes. My assumption is that your version of PHP is first checking if the value exists in that array in case it needs to overwrite the value. You would probably eliminate that error by resetting it by doing $data = array() before u set the values. I would need a bit more info to figure out what's up with $answers though.

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.
