关于ASP与ACCESS的连接问题,(急急急)请大家多多帮忙

请问这段代码问题出在哪里?

function GetSQLRecordset(strSQL,FileName,TableName)
set objConn=server.CreateObject("ADODB.Connection")
objConn.ConnectionString="Provider=Microsoft.jet.OLEDB.4.0;"&_
"DataSource="&server.MapPath(FileName)
objConn.Open '此处报错
set GetSQLRecordset=server.CreateObject("ADODB.Recordset")
GetSQLRecordset.Open strSQL,objConn,adOpenKeyset,adLockPessimistic,adCmdText
end function
