pardon me for not made myself clear enough, what i expect to happen is when user choose the *receipt type == Purchase Order* so the field of *Purchase Order No* *become mandatory field *(either using : notnull = True, required = True or requires = IS_NOT_EMPTY() ), so how can i achieve it using web2py way?
