Display a piece of text if TWO boxes are checked

Hello,
I understand how to show and hide another item when using a radio button Yes / No using the Events tab of that element.
​
However, How do I show / hide another element if two radio checkboxes are selected as 'NO'. For example:
​
Question 1: YES / NO
​
Question 2: YES / NO
​
HTML text block (hidden on load)
​
If both of these independent questions are answered NO then the HTML text block is displayed.
​
Does that make sense? How can I achieve this?
​
Thanks

Hi Lee,
​
You probably need to call a JavaScript function On Change for the two boxes and have that change the display CSS for the HTML block.
