How can I call a function into a function? My problem is: I'm trying to calculate a tax(inss) over a employer salary. I created a function called inss that do it correctly, but when I create another one to show more attributes (inss is not a attribute, it is calculate over a salary) I receive a record (like {1,Mary,32.45} not a tuple. How can I solve it?
