Attribute Wizard Pro, minimum quantity of product options selected

Avg Bid (USD)
Project Budget (USD)
$30 - $50

Project Description:
Recently I installed Attribute Wizard Pro module to my Prestashop 1.5.2. shopping cart. By default, Attribute Wizard Pro (or maybe Prestashop too) require at least ONE product option (attribute value) selected by the customer in order to be transferred to Shopping Cart Summary (I guess this is only in the case when the product is sold just as a combination of various attributes, which is my case). If customers do not select (when using checkbox) ANY product option (or attribute value) and then click 'Add to cart' button, they will receive a warning 'You have to select at least one product option'. My goal is to modify the codes so that instead one product option, costumer (buyer) need to select a minimum of x number of products. The minimum I will require is 3 product options (attributes) selected, but I would like to be able to modify that number based on consumers feedback. I am familiar with some basic code languages (PHP, HTML, MySQL) but I still need somebody to provide me with all the modifications in order for that to work. Many thanks!
