In your sub-selects, the where clause referenxces Q0 from the outer
select... they should probably reference Q2 and Q3. Also... according
to the table info you gave, afaik they should reference Q2.NSEW AND
Q3.NSEW instead of DIRECTION. I don't believe these have to be
sub-selects incidentally, although I don't have time to write out the
alternate syntax at the moment...

at first glance I don't see any attempted conversion from varchar to
float, unless Q0.DIRECTION happens to be a float column. It wasn't
mentioned in the table info.
