标题：求助~~~索引-1不是负数就是大于行数 问题~~

求助。。

不知道为什么在点击出库窗口-保存的时候，老是出这个错。。

条件是物料号在库存里不存在的时候

代码我调试过，定位的差不多是下面一段。

谁能帮我解答一下，谢谢

 With Tables("库存")
                                                                        Dim flag As Integer
                                                                        flag = .Find(cstr(m1),0,"物料号",False,True,True)
                                                                        If flag > -1 And .Rows(flag)("可用库存") >= quantity Then
                                                                            .Rows(flag)("可用库存") = .Rows(flag)("可用库存") - quantity
                                                                            .Rows(flag)("当前库存") = .Rows(flag)("当前库存") - quantity
                                                                            '.Rows(flag)("库存总价") = .Rows(flag)("库存总价") + amount
                                                                           
                                                                            With Tables("出库")
                                                                                If .Current IsNot Nothing Then
                                                                                    .Current.Locked = True
                                                                                End If
                                                                            End With
                                                                        ElseIf flag > -1 And .Rows(flag)("可用库存") < quantity Then
                                                                            e.Cancel = True
                                                                            Messagebox.Show("   实领数量不能大于可用库存数量!", "提示", MessageBoxButtons.OK,MessageBoxIcon.Information)
                                                                        Else
                                                                            e.Cancel = True
                                                                            Messagebox.Show("   当前输入的物料号在库存中不存在,请输入正确的物料号!", "提示", MessageBoxButtons.OK,MessageBoxIcon.Information)
                                                                        End If
                                                                    End With

参考下面的：

看看问题出在哪一行。

注意：

ElseIf flag > -1 And .Rows(flag)("可用库存") < quantity Then

应该改为：

ElseIf flag > -1 AndAlso .Rows(flag)("可用库存") < quantity Then

类似的全部改！！！

汗，果真如此。。。

and andalso。。。
