Here seems to be your problem. Change these String comparisons from == to
.equals()
// build dynamic content
if(interest.equals("")) {
out.println(buildDefault());
}
else if(interest.equals("Procedures ")) {
out.println(buildProcedures());
}
else if(interest.equals("Cafeteria")) {
out.println(buildCafeteria());
}
else if(interest.equals("Maps")) {
out.println(buildMaps());
}
