为什么我的变量传不过去

[ximen]

现有：
a.asp
.
<input type="submit" name="Submit" value="Submit" onclick="javascript:courseselected()" >
<script language=JavaScript>
function courseselected()
{
couseselected=3721;
window.location.href = "b.asp?count1=" +couseselected;
}
</script>

b.asp
<%

dim b
b=request("count1")
%>

为什么在b.asp中得不到任何值

[fason]

<%=request("count1")%>

[心云意水]

<%

dim b
b=request("count1")
response.write b
%>
