I would like to create a cascading radio button with 'How many fault claims in the last 3 years/ How many of these last 1 year?
Eg : How many fault claims in the last 3 years have 0,1,2,3,4 5+ buttons.
If I select 2, I have a new radio button (how many of these fault claims in the last 1 year) with 0 ,1 and 2 as the options.
And I assume if they select 3 then you want options of 0, 1, 2 and 3 for the second question? Same for 4 and 5+?
Yes, that is right.
Note that your field Ids may differ.
Format the appearance of the radios as you please and it should behave something like this:
