Please ensure that you choose your country followed by filling in the box below for "county/state". Failure to fill the last box will result in customers being unable to checkout. For customers who come from countries where there are no county/states, simply fill in the name of your country again. For example, customers from Singapore must choose "Singapore" in the "Country" box, followed by typing "Singapore" again in the box "county/state".  If you are unable to fill in the "county/state" box, simply click on any other country. Click on the country of your choice again and press the "Tab" button on your keyboard and you will be able to fill in the "county/state" box. Alternatively, you may email us at customercare@ecoverve.com.sg if you still encounter any problems.
