    1. COWell, what does tasklistout.csv look like? I'm betting some lines don't have five values separated by "," but a single one.

    3. COI don't believe this is a duplicate. I know what the error 'Undefined Offset' is... it means something is wrong with returning the array value of that index... but what I'm asking is what is CAUSING that error.

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.
