小弟我这样如何去不到表单的值呀？

我这样怎么去不到表单的值呀？~~~~~~~~~~~~
<form   name= "form1 "   method= "post "   action= "savequanxian.asp?userid= <%=rs( "userid ")%> ">
<%if   rs( "hfqx ")=true   then%>
<input   name= "ishf "   type= "radio "   value= "true "   checked= "CHECKED ">
<input   name= "ishf "   type= "radio "   value= "false ">
<%else%>
<input   name= "ishf "   type= "radio "   value= "true ">
<input   name= "ishf "   type= "radio "   value= "false "   checked= "CHECKED ">
<%end   if%>
</form>
-----------------------------------
接收权限代码如下
response.Write(request( "ishf "))


为什么是空值呀？

------解决方案--------------------
response.Write(request.getParameter( "ishf "))
