帅哥们帮我看看这个asp的instr函数与Split函数怎么用？？我现在写的是错误的怎么改正呢？

 strValue=request.form("bh")
strValue=Split(strValue,",")

sql="select * from tuikuan "
if instr(rs("bh"),"&strValue(1)&")>0 then 

response.write"<SCRIPT language=JavaScript>alert('订单编号重复！！');"
response.write"javascript:history.go(-1)</SCRIPT>"
else
