using Eval here is a bit out of date - try
currentWord = this["gap"+currentGap].gap_txt.text
> currentLength = currentWord.length;
> newText = "";
> correctText = gWords[currentGap];
> lastLetter = 0;

make sure you use 'var j=0' here, otherwise you could cause problems
elsewhere in your code (in fact, you may need to do this with several other
variables here, including lastLetter, newText and correctText)

> eval("gap"+currentGap).gap_txt.text =
again, this["gap"+currentGap].gap_txt.text =
> gWords[currentGap].substr(0, currentLength+1);
> eval("gap"+currentGap).gap_txt.setTextFormat(numFormat);

Now, when is this happening? If it's on a keyDown, you might want to think
about doing it on an onChanged event instead.
