Hi everyone,
I have the following equation and I have to add that the numeric value can only be integer to avoid decimals in my answers. How do I do so? (is_empty(self.sq_SQ01comment) or is_numeric(self.sq_SQ01comment))  and (is_empty(self.sq_SQ02comment) or is_numeric(self.sq_SQ02comment))  and (is_empty(self.sq_SQ03comment) or is_numeric(self.sq_SQ03comment))Thanks, Yasmeen

Hi, Yasmeen
so you have to use a different function.
Please, read the manual about all implemented functions.

And: This is obviously not an "Installation & Update Issue"
