reading through this I found someone offer a fix for the save button issue. I corrected the code and now the save button actually registers but it brings up this error msg

1146 Table 'peimei_zc11.products_with_attributes_stock' doesn't exist
in:
[UPDATE products_with_attributes_stock SET quantity = '31' WHERE products_with_attributes_stock.stock_id =416 LIMIT 1]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
