More help with conditional formatting?

Hi Everyone, 

I was wondering if you all could help me come up with some formatting for this form that I'm working on. 

My goal is to have in the "What category do you want your listing under", depending on what they choose, another dropdown menu for subcategories comes up. 

Currently I have the formatting set so that if the field is empty, all the subcategories are hidden, which is great and what I want, but  I can't figure out how to get it so that for those subcategory dropdown lists, only the relevant one shows up dependent on the selection for the first dropdown list, not all of the options. 

Example:  Someone selects "Area" as the category they would like, and then the "Area" subcategory dropdown field shows up, but not all the others. 

Would anyone be willing to clone my form with correct formatting, or maybe tell me what I can put in? Thanks!

Please review the clone version of your form:

I have added the following rules:

Basically, what needs to be done is just make the rules for the fields to show. By making the rule that shows the field, your are implicitly stating that the field is hidden by default, unless the condition is met.

Do let us know if you need further assistance. Thank you.
