This extension check if is possible add the quantity selected in product page into the cart and show a message below the "add to cart" button or the product option that has not enough stock
Basically:
- check the number of the current product already included in the cart [in cart]
- check the number in stock for the product (valid for product with and without options) [in stock]
- Check if it is possible to add the quantity selected => [quantity] + [in cart] <= [in stock]
- Show errors in case not enough stock is detected
All Opencart versions: vqmod and ocmod version included


UPDATED 2020-09-06:
- Validation message is programed to appeared in two ways
- 1st after the "add tocart" button ,as a text. This is the default option
- 2nd as a dialog (javascript alert) this happen if your theme has been modified or you are using a commercial one (the code needs a location to show the default message and you current theme code does not contain that secction).
