[SOLVED] BLYNK blink - what wrong?

led9.on / led9.off ( V9) - work
Blynk.virtualWrite(V9, HIGH); / Blynk.virtualWrite(V9, LOW); - d’nt work
App - android 1.15.3
lib - Blynk v0.3.9 on Arduino Nano

byte stanled9 = HIGH;
void stanvLED9()
  stanled9 = !stanled9;
  if (stanled9 == 1)
 // Blynk.virtualWrite(V9, HIGH);
  else {
  //Blynk.virtualWrite(V9, LOW);

Please see documentation - http://docs.blynk.cc/#widgets-displays-led

ok - but above:
“Imagine you have a LED Widget connected to the Virtual Pin V1 in the
app, and a physical button attached to your hardware. When you press a
physical button, you would expect to see updated state of the LED Widget
in the app. To achieve that you need to send Blynk.virtualWrite(V1, HIGH) when a physical button gets pressed.”

Hm. Nice catch. Thank you. Fixed.
