Because if $ll == "NZ", then is != "AM", so the left half evaluates to
true, so the entire check evaluates to true. In fact, this statement will
always return true, since a variable can never be two values at the same
time. :)

Well, do you want
if (($ll != "AM") && ($ll != "NZ")) {
by any chance? So, $ll is neither AM or NZ?
