john, you need to make sure the non-aggregate columns in the SELECT list are
all in the GROUP BY

you also need to straighten out some of the other clauses

the GROUP BY goes at the end, the ON should ideally link two columns, one
from each of the tables being joined, which appears to be what you've got in
the WHERE, which, when using JOIN syntax, should contain only filter
conditions, not join conditions

i realize this could all be somewhat overwhelming for someone new to sql
