How would I use the Field Validation module with Addressfield to make just city and province/state required?
On your node type field administration page, click the validate for your address field. Click the Required field validator link. On the validator form you want to:


Add your arbitrary Rule name (e.g. Address State)
In Column, select locality or administrative_area for City &amp; State respectively.
Add your custom error message in the Custom error message field.
Click Add rule to add the validator.


Once added for both city/state this will force the address field's city/state to be entered.
