Microsoft VBScript 编译器错误 '800a0408' 无效字符 高手来来来,感激不尽

该博客主要讨论一个ASP CMS中的VBScript代码问题,作者遇到了'Microsoft VBScript 编译器错误 '800a0408' 无效字符'的错误。文章提供了具体的if条件判断处理函数,函数试图解析并替换代码中的if结构。当遇到错误时,删除红色标记的代码,刷新前台,然后再恢复,错误会暂时消失。作者寻求高手帮助,以理解并解决这个问题。

这是一段ASPCMS IF判断代码,有时候行,有时候不行,出现

Microsoft VBScript 编译器错误 '800a0408' 

无效字符 

代码中红色的代码,如果删了,回到前台刷新,在恢复,前台刷新就能用了,

高手指点,分不多。感激不尽,好人好报哈~
