Hm, could we see a self-contained example, ie with the underlying
table/view definitions too? Probably don't need any sample data
for this type of problem, but I'm unexcited about trying to reverse-
engineer your table definitions enough to reproduce the problem.

I'm wondering why this didn't already fail at "counts.count", because with
the "AS howmany" in place, that sub-select isn't returning any column
named "count". I kind of suspect user error due to ambiguous column
names, but the details aren't obvious.
