function TrimText(limmit:Number, area, textVar) {

    var lengthF1:Number = [textVar].length;
    trace(lengthF1);
    var charLimmit:Number = limmit;
    for (var i:Number = 0; i<=charLimmit; i++) {
        trace(i);
        if (i == 0) {
            textcut = [textVar].charAt(i);
        } else {
            textcut += [textVar].charAt(i);
            trace(textcut);
