As3+PHP错误

我使用as3 votingpoll获取此错误。 我不明白怎么了，因为我只知道基本的编码。 我真的需要让它为学校的项目工作

希望任何人都能帮助我！ 非常感谢

TypeError: Error #2007: Parameter text must be non-null.
at flash.text::TextField/set text()
at Onlinepoll_fla::WholePoll_1/completeHandler()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()

AS3代码请求：

PHP代码：

---

显然，event.target.data.return\u msg或event.target.data.choice1Count等变量为空

首先检查PHP脚本是否回显了正确的响应$my_msg或$choice1Count也可能为空。如果PHP脚本正常，请尝试在completeHandler方法中跟踪这些值：

trace("message : " + event.target.data.return_msg);
trace("choice1Count : " + event.target.data.choice1Count);

谢谢你注意到有人能帮忙吗？
