Error compiling for Arduino Mega 2560

[RavenLeox]

@RavenLeox

if (targetDistLv2 < 20) // Less than 10cm
{
SLid.write(90);
delay(1000);// Servo move to 100 degrees
}
else
{
SLid.write(0); // Servo move to 0 degrees
}
}

void loop()
{
Blynk.run(); // Run Blynk Apps
timer.run();
//LidMove();// Run Timer
}

Thanks, it works. The error of compiling is done and another thing occurs.

1. Done compiling and upload to the board.
2. I click the blynk-ser, to change the COM port but it immediately run with COM 1 even though I using with COM 3
