I want to block the bouttons until the fingerprint test match an enrolled finger

Using Arduino Project Guidance
1

in void loop() i need bouttons(); work only if the fingerprint is found and true.
not that good in programming so i'll be really apperciated.

If you find and recognise a finger print set a boolean variable to true. Only call the bouttons() function if the boolean is true

3 
void loop() {
  Empreinte();
  if (NOM != "") {
    NOM = "";
    Bouttons();
  }
}

void Empreinte() {
  NOM = "";
  getFingerprintID();
  if (empreinte.fingerID == 1)NOM = "ahmed benhamad";
  if (empreinte.fingerID == 88 )NOM = "mondher ayeb";
  if (empreinte.confidence >= 60) Serial.println(NOM);
  delay(50);
  empreinte.fingerID = 0;
}

thanks bro , it didn't work but u give me a huge hint wich it made it work

void loop() {
  Empreinte();
  while (NOM == "ahmed benhamad" || NOM == "mondher ayeb") {
    Bouttons();
  }

}
