Need Subforms fields for Rules Condition
Need to figure out how to use a form field in the subform to show/hide sections or fields in the main form. For example, on this form the sub form allows someone to add an entry for each room in a house, based on which rooms they entered need to then only show relevant sections on main form to gather more details about the features of each room.... 
It makes the form, extremely more useful and intuitive to only show the feature sections based on the entries int he subform. If there is another way to do accomplish this, please advise on options...
