How do I set up variants to require/force a customer to make a choice? I want them to tell me what size ring or shirt they want...and it looks like if I don't require it and if they forget to choose, it will default to whatever line is visible when the page loads.

I would be curious to find this out as well..

Good Question!

Yeah.. I wonder why there is not a checkbox like the "display surchage" , etc that says required or something.

Very nice idea and very good to have. The first option needs to default to
------Select--------

Me too. I find that those 'options' are abit too far away from the 'Buy' button.

I would also really like the field to be required and closer to the "Buy" button.
