I found this bug, how to fix it?
round needs a number not a string.
What we can use if I want to show something organic or not organic?
So you don´t want to use a number? Why do you want to use the round block? Can you explain the use case?
The error message is complaining about the value 'None'
Look familiar?
Where did you use 'None'?
It's the not found return from the classifier.
So now the question is, what did the classifier return, in all its glory?
Drop the result into a Label or use Do It
