3 fields: source (text), description(text) and length (time). I sort
by source and description then...
I have a 2 summary fields in 2 sub-summary parts. One summary field is
a count of number of fields in the sort, the other is total length.
The count always works correctly, the total length works for some and
not others. All length fields are time, all are full, sort works fine.
The incorrect answers seem to be short of the correct total. As I said
some of the summaries (total length) are correct.
Any suugestions, thanks in advance for the help.
