I' m creating a survey were the recipient can answer giving a score from 0 to 10. I want to save the answer in an data of type Integer.
I've chosen Integer 8 bit (-128 to 127) as data type but when the user select 0 as answer then the score is not saved (if i mark the answer as mandatory it doesn't go to the next page).
If i define that the value linked to the label 0 is -1, then the value saved in 255.
It seems that even if the data type chosen is Integer 8 bit (-128 to 127), it cannot store non positive values.
I would like to store 0 in the database to have clean data.
