有关下拉菜单选中某项的问题

[kourr2004]

我想请问大家!
有一个下拉菜单放在<form>里面,提交时若选中某项,提交后把此项显示出来.默认的老是显示第一项.请各位高手指点下,很急!!!!
代码如下:
<form method="post" action="" name="frm">
<div align="center" class="dhl">请选择
<select name="yearstr">
<% for i=year(now) to year(now)-1 Step -1 %>
<option value="<%=i%>"><%=i%></option>
<% next %>
</select>
年第
<select name="monthstr">
<% dim i
for i=1 to 7 %>
<option value=<%=i%>>
<% if i=1 then
response.write "1-2"
elseif i=2 then
response.write "3-4"
elseif i=3 then
response.write "5-6"
elseif i=4 then
response.write "7-8"
elseif i=5 then
response.write "9-10"
elseif i=6 then
response.write "11-12"
elseif i=7 then
response.write "年终考核情况"
end if%></option>
<% next %>
</select>月
<input type="submit" value="确认">
</div>
</form>
