Does anyone have any experience installing the Product Extra Fields v1.3c contribution. I've installed it on my ms2 max shop, but when I click a product, I get the following error:

1064 - You have an error in your SQL syntax near 'ORDER BY products_extra_fields_order' at line 7

SELECT pef.products_extra_fields_name as name, ptf.products_extra_fields_value as value FROM products_extra_fields pef LEFT JOIN products_to_products_extra_fields ptf ON ptf.products_extra_fields_id=pef.products_extra_fi elds_id WHERE ptf.products_id= ORDER BY products_extra_fields_order

[TEP STOP]

Any ideas?
