Hi

I am working on an assignment and trying to write a function that will search against a hashmap and return the found string as a a variable (see below).  I keep getting 'Return type for the method is missing' - I haven't called the setup or draw functions - just trying to get this to work on its own for the moment and not sure if that is possible.

Any tips would be gratefully received!

Thanks

//puts rules into map
HashMap rulesMap = new HashMap();
rulesMap.put("bg", "ac");
rulesMap.put("em", "ns");
rulesMap.put("pq", "rt");
rulesMap.put("ac", "dj");
rulesMap.put("ns", "pq");
rulesMap.put("ki", "uv");

//sets goal variable
String goal = "dj";

//function to search rules for antecedent and returns corresponding lhs
String searchRules(String goal) {
String leftHandSide = (String) rulesMap.get(goal);
  if(leftHandSide != null) {
  println("Value mapped to lhs is " + leftHandSide);
  return leftHandSide;
  } else {
    println("No Value mapped with key");
  }
}
