dreamweaver+asp制作修改密码页面~

我想制作一个修改用户密码的页面但是我不知道该怎么做，请求高手帮忙 旧密码： 新密码： 确认新密码：有图文最好，，谢谢~

表单你总会做吧？
asp部分
<%
public Sub alert(text, url)
response.write "<script>alert(""&text&"");"
if url = "" then
response.write "history.back();<&#47;script>"
else
response.write "document.location='"&url&"';<&#47;script>"
end if
response.end()
end sub
user = user
pass = Request.form("旧密码")
pass_new = Request.form("新密码")
pass_newto = Request.form("确认新密码")

if pass = "" then alert "请输入旧密码", ""
if pass_new = "" then alert "请输入新密码", ""
if pass_newto = "" then alert "请输入确认新密码", ""
if pass_newto <> pass_new then alert "两次密码输入不一致", ""

Set rs = conn.execute("select 密码字段 from 会员表 where 密码字段 = '"&pass&"' and user = '"&user&"' ")
if rs.eof then
alert "旧密码错误", ""
end if
Set rs =nothing

Set rs = conn.execute("Update 会员表 Set 密码字段 = '"&pass_new&"' where user = '"&user&"'")
alert "密码修改成功", "passUpdate.asp"
Set rs = nothing
%>

更新你会不会，修改密码就是更新字段内容。
