Sir, you can't use a nested join between INNER JOIN and ON. The only
thing that can go between INNER JOIN and ON is a table name. With
inner joins, it doesn't matter what order the tables on joined in.
Rewrite your FROM clause so that you always have 'INNER JOIN <table
name> ON'. Or you can replace the INNNER JOINs with commas and move
the ON conditions to the WHERE clause.
