Sorry, one last little thing on this. Its not a deal breaker, as its aesthetics not functionality. But I had a little bit of JS that was styling the drop downs, which don't work with the WA dynamic dropdowns. I suspect its just a case of JS conflicting and not playing ball together.
If you log in to the site, find a lodge and click on update product in the top right, the dynamic dropdowns work as they should with continent and country.
If you change the URL from index.php... to index2.php you can see the dropdowns with the styling, which don't work.
The only different code is:
Don't worry if its anything other than some simple JS thing, as obviously its not the WA bit that isn't working.
