Hi Vanessa,
First, is this a repeating collection where you have multiple sections which each have their own "No Work Experience" checkbox and assorted other fields? Or was the image just pasted twice?
Second, this should be able to be accomplished by field rules (see Ming's example above; you can add other criteria under "Company Name" line to account for other fields). Could you upload an image of the field rules you configured which did not work? Also did you have any existing CSS or JavaScript operating on any of the fields in question?
Cheers
