这个用日期算总额的算法错在哪里？
为什么没有实现加法 也没提示错误呢？

<%
rq1=request("rq1")
rq2=request("rq2")

dim Conn, sqlstr,temp

set Conn=server.CreateObject ("adodb.connection")
Conn.open "driver={Microsoft Access Driver (*.mdb)};dbq="&server.mappath("customer.mdb")

set rs=server.CreateObject("adodb.recordset")

rs.Open "select sum(t2) as temp from customer where singsdate>="&rq1&" and singsdate<="&rq2,conn

response.write rs(0)

rs.close
set rs=nothing%>

rs.Open "select sum(t2) as temp from customer where singsdate>='"& rq1 &"' and singsdate<='"& rq2 &"'",conn,1,1

这样试试看

多谢老大！
