以前没做过asp，一个很简单的问题

[poppoptian]

Set obj = Server.CreateObject("Telesion.CAutoForm")
obj.RefName = "worker_info_430"
obj.ConnectStr = application("dsn")
obj.Mode =3'
call obj.Format
Set coll = obj.Lines //这是69行
For Each c In coll
Response.Write( c + Chr(13) + Chr(10))
Next

这个程序怎么报这个错啊？
Item cannot be found in the collection corresponding to the requested name or ordinal.

/smartbld/doc_manage/worker/worker_list.asp, 行69
