Change color of rectangle based on word in textfield

[nitrokid]

Hi

I have a textarea (st1a) and a red rectangle above it (st1b). When the word 'England' is entered into st1a, I want st1b to change to Green. When anything else is entered into st1a, then st1b should be red

I've tried this :

on(change){
if (st1a.text == "England") {
_root.st1b.setRGB(0x66CC33);
} else {
_root.st1b.setRGB(0xFF0000);
}
}

However, othing happens when I enter England into the textarea. The rectangle just remains red. I am very new to actionscript and flash, so I wouldn't be suprised if I've got it totally wrong

Any help would be much appreciated

code on main timeline do not attach to textarea or rectangle movie clip

var listen:Object = new Object();
listen.change = function(obj) {
if (obj.target.text == "England") {
clipColor = new Color(st1b);
clipColor.setRGB(0x66cc33);
} else {
clipColor = new Color(st1b);
clipColor.setRGB(0xFF0000);
}
};
st1a.addEventListener("change", listen);
