[求助] 操作苻丢失错误

错误类型：
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] 语法错误 (操作符丢失) 在查询表达式 'zt_ id = 1' 中。
/lt_topiclist.asp, 第 41 行
这几行的代码：
Set toplist = Server.CreateObject("ADODB.Recordset")
toplist.ActiveConnection = MM_web_STRING
toplist.Source = "SELECT * FROM zhuti WHERE zt_ id = " + Replace(toplist__MMColParam, "'", "''") + " ORDER BY zt_ id DESC"
toplist.CursorType = 0
toplist.CursorLocation = 2
toplist.LockType = 1
toplist.Open()

toplist_numRows = 0
%>
这有什么问题呢　？
请指教啊！
