我附上代码吧
set rs = server.CreateObject("ADODB.RecordSet")
rs.open "Select 预定场馆名,预定时间段,预定日期 from book where 预定场馆名='"&Request.Form("place")&"'",dbconn
if NOT rs.BOF then
rs.movefirst
end if
if rs.Eof then
a=2
else a=0
end if
do while a=0
for i=1 to Request.Form("time").count
if rs("预定场馆名")=request.Form("place") and rs("预定时间段")=request.Form("time")(i) and rs("预定日期")=request.Form("date") then
a=1
exit do
end if
if rs.EOF then
exit do
end if
next
rs.movenext
loop
if a=1 then
%>
<script language="javascript">
alert("场馆已被预定,请重新选择!")
location.href="bactbook.asp"
</script>

if rs("预定场馆名")=request.Form("place") and rs("预定时间段")=request.Form("time")(i) and rs("预定日期")=request.Form("date") then
这一行一直提示(0x80020009)
