IR Remote code error

void setuo() {
 fermati ();
void fermati() {

   digitalWrite(9, HIGH);   //Disengage the Brake for Channel A
   digitalWrite(8, HIGH);   //Disengage the Brake for Channel B

Hi, I recently bought a controller for Arduino, but creating the program gives me errors on the call to subprograms

'fermati' was not declared in this scope

this is the error

Your code is incomplete.

What does it have to do with an IR remote code?
