sorry i forgot the formatting...

John,

You need to fill the "NOT DELETED()" clause in the filter box rather than adding it to your expression clause:
>
Field      Type       Expression     Filter
myfield    Primary    myfield        .NOT. DELETED()
>
You might want to add a regular index without the filter clause to speed up performance (rushmore)
