Hi im new to coding and i keep getting a issue with my code. This is the error code that pops up too few arguments to function 'bool ledcAttach(uint8

@anthonyss is it possible that you Ctrl-V your code twice?

make

  //Set up PWM for motor speed
  ledcAttach(rightMotorPWMSpeedChannel, PWMFreq, PWMResolution);
  ledcAttach(leftMotorPWMSpeedChannel, PWMFreq, PWMResolution);

Thank you this seemed to fix the code.
