I have a sign up form that includes a CF radio named package. This radio has 4 options and each corresponds to a product. At the moment the user needs to select one of these options but I want to set the default value to be based on the url parameter.
On the previous page the user selects which package they want but currently all these links just go to the same sign up page. I can easily add custom url for each package so I'm wondering if radio on the sign up form can listen for url and depending on it's value set a default radio value?
