PDO Exception thrown when filtering by Terms

When filtering products by terms for given discount PDO exceptions were thrown on line 935 of uc_discounts_alt\uc_discounts\uc_discounts.module.
This seems to be caused by a typo on Line 943:
$query .= ' INNER JOIN { taxonomy_index} tn ON p.nid=tn.nid
white space removed to
$query .= ' INNER JOIN {taxonomy_index} tn ON p.nid=tn.nid
which now works OK
