How can I have 2 zones with 2 diff shipping rates in India?

I have installed and set up litecart, but I am running into a snag (or more likely my ignorance!)

I want to sell only in India and I need 2 shipping zones.. South Zone has free shipping (which includes 5 states) and Rest of India has a weight based shipping.

When I try to create zones the list box does not show any states but only a blank list

Any pointers would be greatly appreciated

Zones/states are defined in Admin -> Countries -> Edit Country
If you need to add a large amount of zones you can handpick from this add-on.

For south zone you either don't need to specify shipping. Or You can put 999:0 for it's weight table.
