I have posted this at WooThemes as well since this involves their GF Extension.
When the customer is supposed to choose a lens they are presented 4 choices and can see what the cost is:

then, when a choice is made the other figures recalculate based on the selected price:

how can this be stopped? I think it's potentially confusing.
An additional question - I had added a reset button within this portion of the form in case a customer wanted to start all over. It reset their choices but did not remove the costs associated with those choices.....hope that makes sense! Anyway, is there a way to reset the form completely?
