To all those who are having a problem/getting error:
1. Make sure that you height/weight is in proportion on the BMI scale
2. Fill up all mandatory fields
3.
MOST IMPORTANT
DO NO USE . , / - ANY WHERE IN YOUR FORM
..USE SPACES IF REQD
I've tried innumerous times since the last 3 days..the 3rd option worked out finally !!
Good luck!
