What am I missing? Am I heading in the right direction?

I have tried this several different ways and can't seem to get my head around what I am doing wrong. Can someone help point me in the write direction?

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 character = lastName.CharAt(0);
      if(character < 'n') {
        line = 1;
      }else{ line = 2;
           }
    return line;
  }

./ConferenceRegistrationAssistant.java:7: error: cannot find symbol
    char character = lastName.CharAt(0);
                             ^
  symbol:   method CharAt(int)
  location: variable lastName of type String
1 error

The error message "cannot find symbol" usually means a spelling mistake.

You've made a couple mistakes with case:

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 character = lastName.charAt(0);//HERE
      if(character < 'N') {//PROBABLY HERE
        line = 1;
      }else{ line = 2;
           }
    return line;
  }

}
