下面的代碼在Adobe ColdFusion的工作，但由於遷移到Railo給了我以下錯誤：數組的索引[0]無效。指數必須是正整數
錯誤消息：無效的指數[0]數組。索引必須是正整數（1,2，3，...）
錯誤是在線路的起始：local.arrChartDataResult = addPercentageData（local.arrChartDataResult）
知道爲什麼這是案件？

嗨@亞當卡梅隆感謝您的迴應。它確實表明錯誤是在我的鐵路錯誤中指出的。但是，現在，我要我的更新完整的誤差OP :) – GrantU
@Adam卡梅隆我還增加了全功能上面，如果這將有助於OP。非常感謝 – GrantU
我跑Railo 4.0.4.001最終端口：8888 Ubuntu服務器12 – GrantU
