I get the following error.

@anon73444976

The code you didn't post doesn't have a setup function or a loop function.

@badpaddler1
1. Check that when you open the IDE, it comes up with the following two functions:

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

2. Check that you can compile and upload the blank sketch of Step-1.
