I've installed the add-on with no problem, but I kept getting this error:

146 Table '[...]TABLE_PRODUCTS_STOCK' doesn't exist
in:
[select quantity from TABLE_PRODUCTS_STOCK where products_id = '18' AND quantity > 0]

I tried following the instructions given to someone else who had the same problem, but nothing I do on the stocks page seems to change the outcome--I still keep getting the error.

I'm running Zen Cart 1.3.8...

This add-on is exactly what I need, but I can't figure out what's causing this problem. I tried uninstalling everything related to the mod (I'm not sure if I did a clean job, overwrote files, dropped the relevant tables in the database), and the problem persists.

Any advice?

Thanks!
