ADO数据库添加数据一个正常一个出现，不知道那里的问题？

Combo1.AddItem BookRs.Fields(1)
BookRs.MoveNext
Next BookRsCount
BookRs.Close
CancelADOConn
End Sub

frmLanguage.frm

Option Explicit

Private Sub cmdAdd_Click()

Set BookRs = BookADOConn(BookRsStr3)

For BookRsCount = 1 To BookRs.RecordCount
Combo1.AddItem BookRs.Fields(1)
BookRs.MoveNext

CancelADOConn
End Sub

其中添加Type的没有出现错误，但是添加Language的出现 Open Recordset错误

哪位，前辈帮忙看看
