Actionscript 3 ошибка 1010

The counter displays sprites in place of number values. More experienced programmers have given me a clue. Why am I getting error # 1010.

Secondly, what am I not seeing that’s so obvious? I wish I went in to this with a better foundation in actionscript 3, but I’m reading and doing my best.

WHAT I SEE

-Error #1010: A term is undefined and has no properties
-is the associative string is fooling me? «maybe I set no values, duh»
-are the property of my symbols are set wrong?

Счетчик отображает спрайты вместо числовых значений. Более опытные программисты дали мне ключ к разгадке. Почему появляется ошибка №1010.

Во-вторых, что такого очевидного я не вижу? Хотел бы я приступить к этому с лучшей основой в ActionScript 3, но я читаю и стараюсь изо всех сил.

ЧТО Я ВИЖУ
-доллар обозначает переменную или массив «$ числа»
-импорт flash.utils.Dictionary; «обозначает ассоциативную строку»
-Ошибка № 1010: термин не определен и не имеет свойств.
-это ассоциативная строка меня обманывает? «может я не установил никаких ценностей, да»
-установлены ли свойства моих символов неправильно?

СООБЩЕНИЕ ОБ ОШИБКЕ

TypeError: Error #1010: A term is undefined and has no properties.

When testing my project, I got this error :

I don’t understand why and if I change the if statement to something simple it’s all work fine.

This is my code :

The counter displays sprites in place of number values. More experienced programmers have given me a clue. Why am I getting error # 1010.

Secondly, what am I not seeing that’s so obvious? I wish I went in to this with a better foundation in actionscript 3, but I’m reading and doing my best.

WHAT I SEE
-dollar sign indicates a variable or array «$numbers»
-import flash.utils.Dictionary; «indicates an associative string»
-Error #1010: A term is undefined and has no properties
-is the associative string is fooling me? «maybe I set no values, duh»
-are the property of my symbols are set wrong?

It sounds like you are accessing an undefined index in your array in the file NumbersView.as.

_listItems[i]

In your for loop for _listItems:

for (var i:Number = 0; i < 9; i++) {

You set the _listItems to 0 to 8.

Then in your setTime for loop:

for (var i:Number = 0; i < nums.length; i++) {

You go to the length of the Array to access _listItems[i].

Is it possible that the length of this array is more than 8? If so then that could cause the error.
