我是这样写的：
<%
set rs3 = server.createobject("adodb.recordset")
sql1="select sum(in_money_yu) from info_all where user_id = 75"
sql2="select money from user_info where user_id = 75"
rs3.open sqlb ,conn,1,1
rs3.open sqlc ,conn,1,1
if rs3("in_money_dl")>0 then
mm1=rs3("in_money_dl")
mm2=rs3("mbit")
mm3=mm2*mm1
else
mm3=0
end if
response.Write mm3
rsb.close%>
明显这个错了，请问正确的应该怎么写啊？
