类型不匹配: 'mappath'

[zxm1983]

<!--#include file="Conn.asp"-->
<%
Dim UnitName
UnitName=request("UnitName")

response.Write"<h2>"&UnitName&"</h2><br>"
sql="select * from Connection where UnitName='"&UnitName&"'"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,1
'address=rs("connString")

Set conn1 = Server.CreateObject("ADODB.Connection")
DBPath="DRIVER={Microsoft Access Driver (*.mdb)};DBQ="&server.mappath(rs("connString"))
conn1.Open DBPath
%>
报错：类型不匹配: 'mappath'请教各位大侠，谢谢。

rs("connString").ToString();

[孟子E章]

If Not rs.EOF Then
Set conn1 = Server.CreateObject("ADODB.Connection")
DBPath="DRIVER={Microsoft Access Driver (*.mdb)};DBQ="&server.mappath(rs("connString"))
conn1.Open DBPath
End If

另外打印出 rs("connString")看是一个路径吗
