Hi prajakta,
Actually the value(age) you are cheking is actually empty. Thats why this error is coming.
You xan correct this by adding one more expression in the decision where you are checking the negative number..
Add it..
$FarmerPersonalDetails/Age !=0 and $FarmerPersonalDetails/Age > 0
It will work.
Hope it helps!
Hi
Whenever we tried to write expressions, both the left and right sides should not have empty values.
Here your age seems empty, which is why you are getting this error.
