error: expected unqualified-id before 'if' if (send) { but all semicolons are available [closed]

Question

I am getting a compilation error: expected unqualified-id before 'if' . Btu I have check all the semicolons . Please help finding my error. The rest of the message error reads

C:\Users\jecalderon\Documents\Arduino\Codigo_AS7262_Investigacion_V2\Codigo_AS7262_Investigacion_V2.ino:35:1: error: expected unqualified-id before 'if'

Check your braces. Use Control-T to autoformat your code and the error will become apparent.

This is your entire loop function. Everything after this is is outside of the function.

void loop() {
  //lee la temperatura del sensor
  //uint8_t temp = ams.readTemperature();
  //ams.drvOn(); // descomentar esto si quieres usar el led del sensor para hacer medidas
  ams.startMeasurement();  //begin a measurement
  //permite que el sensor lea la data cuando este disponible
  unsigned long currentMillis = millis();
};
