Formula mode error when 'adding' data pills together using '+'
Hi, I was using a formula like this (data1 + data2 + data3) when I encountered some error messages..
Error messages:
1. No implicit conversion of nil into string error
2. Formula received a nil value: undefined method `+' for nil:NilClass
I received the errors on different jobs. One of them had null value in description, the other had null value in amount. I thought that if a data pill was empty/null, then the empty pill would be passed.

Hi Saul,
While using + operation on data pills, If any of the data pill expecting to be empty or nil, It should be handled explicitly by using present? or presence.
Always, when using + with data pills for concatenation, it is a method call. so It tries to evaluate data pills and then concatenate. You have to make sure that pills on both ends should not be nil or empty.
