主题：【求助】如何实现“复选组合框”中的多条件筛选功能的代码，跪求解！！

“组合框”的单一条件筛选功能代码可以实现，求如何用“复选组合框”实现多条件筛选功能的代码。

以下是“组合框”的单一条件筛选功能代码：

Dim Filter As String
With e.Form.Controls("bm")
    If .Value IsNot Nothing Then
        Filter = "部门 = '" & .Value & "'"
    End If
End With
With e.Form.Controls("xl")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "最高学历 = '" & .Value & "'"
    End If
End With
With e.Form.Controls("htxz")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "劳动合同性质 = '" & .Value & "'"
    End If
End With
With e.Form.Controls("zc")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "职称 = '" & .Value & "'"
    End If
End With
If Filter > "" Then
    Tables("采购部在职人员数据库").Filter = Filter
End If

将以上代码如何修改？求“复选组合框”实现多条件筛选功能的代码。比如选2个条件“最高学历 or  劳动合同性质”筛选
