I have an observer function on the event
checkout_cart_add_product_complete that is pulling parameters out of the URL and modifying the cart based on the parameters. This portion is all working fine.
However, there is a block injected by a 3rd party module that sets a value on radio buttons based on a function that evaluates settings in the Magento backend. I would like to override the value returned by this function based on the results of my observer.
What would the best way to go about this be?
