</div>

myText.onSetFocus = function () {  
myText.backgroundColor = yellow; //need to assign a hex coded color to the var ‘yellow’ before!  
};

myText.onKillFocus = function (){  
input = Number (input); //input txt is treated as string by default!  
if input \< 10{  
myText.backgroundColor = black; //or do whatever  
}else{  
myText.backgroundColor = green; //likewise…  
}

notes: you need to set myText.backgroundColor = true; before you use this;  
define colors like yellow = 0xFFFF00;

Helps?
