求教

set rs = Server.CreateObject("ADODB.Recordset")

........
........
<%sqltext="select * from picfiles where code=product and keyno="&prono
rs2.Open sqltext,cn,1,1
pic=rs2("picfile")%>
<TD CLASS="bodytext" WIDTH="40%">
<%if pic<>"" then%>
<img src="../admin/pic_displayacc.asp?keyno=<%=prono%>&code=product" border="0">
%else%>

<%end if%>
</TD>


请问以上有哪些语法错误啊，为何说rs2.Open sqltext,cn,1,1这行类型不匹配？
