When I create Instances through a loop how do I address them?

Hi,

I am trying to create TextField Instances for a crossword puzzle in Flash through a loop and then address them later how do I do this. My Code:

for (var i=0, i<lettersArray.length, i++) {
var a:TextField = newTextField;
//someformatting here like :a.x=i*10; etc.
addChild(a);
}

now I want to say:

if (specificTextbox.text=correctAnswerLetterArray[someIndexNumber]){
_global.Points += 1}

Thanks in advance for looking at my post. :thumb:
