Trouble with the CharS challenge.

I'm stuck on a challenge code. I have to use CharS to compare one char to another char. I thought the syntax for it was

if (lastName.charS() >= 'M')

but i'm getting a class error.

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */

    int line = 0;
    char letter = '';

    if (lastName.charS(letter) >= 'M') {
      line = 1;
    } else {
      line =2;
    }

    return line;
  }

}

What the challenge is asking is to compare the first letter of the last name which would be done by getting the first character of the lastName string. The part in the description saying "chars can be compared using the > and < symbols." is just saying that you can take a char variable and use basic comparisons just like int variables. There is no charS function involved. Its only a typographical issue that makes it even look like it.
