我希望这是我对这个数据库的最后一个问题。我写了一个代码：就是平均一组输入。

Public Sub CalcOverallRating()
Dim li_CalcValue As Integer

If IsNull((Forms![FRM_CSR]![PP1]!CBX_PP1.Value) Or _
           IsNull(Forms![FRM_CSR]![PP2]!CBX_PP2.Value) Or _
           IsNull(Forms![FRM_CSR]![PP3]!CBX_PP3.Value) Or _
           IsNull(Forms![FRM_CSR]![PP4]!CBX_PP4.Value) Or _
           IsNull(Forms![FRM_CSR]![PP5]!CBX_PP5.Value) Or _
           IsNull(Forms![FRM_CSR]![PP6]!CBX_PP6.Value) Or _
           IsNull(Forms![FRM_CSR]![PP7]!CBX_PP7.Value)) Then
    'Don't calculate if any values are null
Else
    li_CalcValue = (Forms![FRM_CSR]![PP1]!CBX_PP1.Value + _
                    Forms![FRM_CSR]![PP2]!CBX_PP2.Value + _
                    Forms![FRM_CSR]![PP3]!CBX_PP3.Value + _
                    Forms![FRM_CSR]![PP4]!CBX_PP4.Value + _
                    Forms![FRM_CSR]![PP5]!CBX_PP5.Value + _
                    Forms![FRM_CSR]![PP6]!CBX_PP6.Value + _
                    Forms![FRM_CSR]![PP7]!CBX_PP7.Value) / 7
    Forms![FRM_CSR].Text270.Value = li_CalcValue
    Forms![FRM_CSR].[Overall CSR].Value = li_CalcValue
End If

End Sub

此外，我在每个表格名称 FRM_PP1 到 FRM_PP7 中都有一个 Call CalcOverallRating。

使用组合框时会出现 Invalid use of Null 的错误。请帮忙

您已将所有条件包含在第一个IsNull()函数中。这些应该是分开的条件：

If IsNull(something) Or IsNull(somethingElse) ... Then

删除左括号和右括号。
