加个hidden（隐藏域）这个吧
<input maxlength=20 name="T4" size=12 type=hidden value="<%call yzm()%>">
在写个判断
<%if request("t3")<>request("t4") then
response.Write "验证码输入错误。请返回重新输入！"
response.end()
end if%>
<%
num=session("yzm")
num_request=request("yzm")
if request("B1")="登录" then
response.write request("T3")
if num <> num_request then
response.write "验证码不对"
else
response.write "验证码正确"
end if
end if
%>
