you can't negate a String, only a boolean.
I've no clue what you're trying to accomplish there so can't help you out.

Are you trying to say "not less than", if so why don't you just say "greater than"?

Edit: Nevermind, I'm an idiot, they're Strings so greater than and less than are not what you want anyway. Doh!

if you want to compare strings use compareTo() method ex: oneString.compareTo(anotherString). if oneString is greater then anotherString the method will return value >0, it it is less --> value <0, and if they are equal -->value =0.

I hope that this will help you.
