Slight modification with Qphoria's Options Plus help plz?

Hi,

I'm using Q's option plus module to allow me to price by whatever option is selected. However, I wish to use this module by having the customer choose the price from the option - not by adding the option price to the product price. I have added all products in as £0.00, and each option price is set.

How can I prevent adding an item to the cart if no option is set or maybe default an option to the first in the list so there is never a situation of an item being added to the cart with a price of £0.00?

Well by default, options plus prevents you from adding a product without options. But The way the cart was designed, your product price should be the price of your lowest option

Instead of:
Product - 0.00
option 1 - 5.00
option 2 - 10.00
option 3 - 15.00

It is designed to be:
Product - 5.00
option 1 - 0.00 (this is the default)
option 2 - 10.00
option 3 - 15.00
