Hi guys, i managed to get this working on my live server (IIS6 + ZC 1.38), but when trying on a local development server ( IIS7 + ZC 1.38) I get the error:

1366 Incorrect decimal value: '' for column 'products_price' at row 1
in:
[INSERT INTO dev_orders_products (orders_id, products_id, products_model, products_name, products_price, final_price, onetime_charges, products_tax, products_quantity, products_priced_by_attribute, product_is_free, products_discount_type, products_discount_type_from, products_prid) VALUES ('22', '183', '', '', '', '0', '0', '0', '1', '', '', '', '', '183:58c0d33b81b1bb9a2143cbe94009071c')]

Any ideas why it doesnt work locally?
