求助,十万火急!!!

请大家帮我看一下我的这个判断语句,帮我找下哪有错误而且请留下解决的办法,万分感谢!
if(form1.File.value.length!=0)
{
var filetype,FileExt,filetypes;
filetype = "rar|doc|jpg|txt|gif|bmp|rtf|ppt|xls|htm";
filetypes = Split(filetype, "|");
FileExt = Extension;
for(int i=0;i<=filetypes.length-1;i++)
{ 
if(filetypes(i) = FileExt)
{  
  alert('文件上传成功!'); 
  }
else
{
alert('禁止上传文件格式:"&FileExt&",请重新选择!');
form1.File.focus();
return false;
}
}
}
还有一个问题Extension是另外一个页面的值,怎么获取到它..
