    2. CO@Stefan -- Your NULL results on the distance column probably means that your math is trying to evaluate a null at some point. I modified my answer for a few things you can try...

    3. CO@Stefan -- BTW -- I'm not good at this kind of math, so I gave 2 potential answers. Essentially, the ISNULL() function says 'if this thing I am evaluating is null, then output a `___`', where "`___`" is whatever you specify. In my samples, I used a zero.

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.
