Wrong output

I am getting issue with the conversion output.It seems like it is not compatible to my theme.This is my website http://data-flair.com . The switcher is not able to convert the currency from usd to inr . It is giving the output 0.00 rs. It is very appreciable if you can give me the proper solution.
Thanks in advance.
