Help with dynamic lookup example from documentation

Hi, can you help me please with a question about the dynamic lookup example in the documentation:

https://www.zoho.com/creator/help/fields/configuring-conditional-drop-downs.html#Create_Dynamic_Lookup

I need to implement a form that, when the user access the form, all the countries and states are available on the dropdown lists, so:

1. If the user first selects a country, the second dropdown list will be updated with only the related states, so he can select a state

2. If the user first selects a state (and don't pre-select the country), the associated country will be selected automatically on the first dropdown list

So, depending on what is selected first by the user (country or state) the other dropdown list will be automatically updated.

Thanks for your help! 

Best regards, Juan
