Check Minimum Product Quantity Before Adding to Cart

Hi,

How can we check the options quantity before adding it to the cart, when options are available.

I tried the solution from Qphoria at http://forum.opencart.com/viewtopic.php ... 75#p244701

But, that only works if there are no options available as it checks against the quantity in the main product info. I have got options for some of the products with quantity field, hence if the product has options, it should check against the quantity field of the options else against the quantity field of the product.

I do have 'Options Boost' and 'Options Price update Redux' installed, if that will make any difference to the code.

Thanks.
Kind Regards,
FM

Any ideas guys?
