[JAVA3D] A regular Java problem

[eb]

Hello everyone. I'm doing this project for a class, and I'm finding that a line in my method isn't being called. It's in an if statement and it's a return statement. Instead of returning the string value it's supposed to, it jumps to the end of the method and prints out (what could be considerered) the last else statement. (by that I mean, if it hasn't met any of the other requirments then it must be this) Here's the entire project, 3 java files/ 3 class files. Try running it(run on Project3). The method I'm having trouble with is the "doSearch(ListNode node, String airportCode)" Thanks for any help in advance.   EB
