Please don't post images of code.. it makes it hard for anyone to debug.

int d;

void setup()
{
  switch (d)
  {
    case 0 ... 5:
      break;
    case 6 ... 10:
      break;
    case 11 ... 15:
      break;
    case 16 ... 20:
      break;
    default:         // > 20
      break;
  }
}

void loop()
{

}

you forgot the last

  default:
    // statements
    break;

Thank you and thanks for reminding me to paste code directly from the app.

the switch structure doesnt allow a range to be represented in that way.

Note - in specifying a range you must use this exact format

case (low value) space three dots space (high value): as shown above.

I'm sure if you delete all but the first case it will still show a compiler error.

You DONT need to have a "default " if the cases cover all possibilities - but in your case if d can exceed 25 its better to have one.

Many thanks johnerrington. I did manage to get it to compile when I removed the range and assumed switch case would only accept a single integer, Your tutorial is the perfect solution. I didn't see that in the switch case reference documentation. Very much appreciate you help. Thank you.

The 'default:' case is not required.
The final 'break;' is not required.
