与父母的矛盾英语作文:哪位高手知道? ASP问题

总是提示INSERT INTO 语句语法错误,是不是数据库设置有问题?下面是代码段:
<%@ LANGUAGE=VBScript%>

<% Dim StrTB,StrMB
StrTB=server.HTMLEncode(Request.Form("TB"))
StrMB=server.HTMLEncode(Request.Form("MB"))
'??????
if StrMB="" Then
iLenMB=255
Else iLenMB=Len(StrMB)
End if
'************************************
DBlink="driver={microsoft access driver (*.mdb)};dbq="&server.mappath("db.mdb")
set conn=Server.CreateObject("adodb.connection")
conn.open DBlink
set cm=Server.CreateObject("adodb.Command")
cm.ActiveConnection = conn
cm.CommandText="INSERT INTO user(name,text)VALUES(?,?)"
set objparam=cm.CreateParameter(,200,,255,StrTB)
cm.Parameters.Append objparam
set objparam=cm.CreateParameter(,201,,iLenMB,StrMB)
cm.Parameters.Append objparam
cm.Execute '这里有错!!!!INSERT INTO 语句语法错误

Response.Write("完毕")
%>
