Thanks for your quick reply.
As I mentioned I'm new to VirtueMart and have only created simple e-commerce before this and detailed documentation seems limited for this great component.
From your experience, how would you go about setting it up the products? I just created a product and added the various multi-variants as child products. I didn't know there was an alternative way, can you provide some more detail, please?
I'll take a look at the product builder, thanks.
I don't like the category page format for the parent, I really wanted it all to function from dropdown menu multi-variants which looks much slicker, smarter.
