Locking the next radio button set after a certain preceding value is chosen
I'm having difficulty finding how to lock radio buttons when a certain value has been chosen in a preceding radio button set.
I have 3 categories in my database. For category "A" in row 1 if "none" is selected I would the following 2 lines to lock and change color so that they cannot be changed. However, if "occasional" or "plentiful" is chosen I want to be able to select them. For category "B" if "none" in row 2 is selected I want the following row to change color and lock, but able to be selected if "occasional" or "plentiful" is chosen. I want the same thing to happen for category 3.
I've come across conditional hiding in my searches, but I want the ability for fields to lock.
