I have set Color Variation using your plugin, The image swapping is working fine. The problem is when a user is clicking on add to cart button without selecting any color its adding to the cart but I want to make the color variation as a required field so that every user has to definitely select the color otherwise it shows an alert "please select any color".Thanks in advance for your reply. Advanced Happy New year....
