нет доступа к массиву

[Max360]

Сегодня наверное какой-то несчастливый день. Как я уже говорил "Дикие лаги" сыпятся один за другим. Вообщем, во время исполнения в Variables все хорошо, и массив виден и элементы его на месте. Но компилятор почему-то выдает ошибку в методе onDel_Click: Error #1010: A term is undefined and has no properties.
