我的一个工作表中有2个宏，它们使 i）从彭博网站的收盘价直接进入工作表[通过按钮触发]（单元格H3：向下）和 ii）如果此新值导致位于单元格K3：downwards中的公式发生更改，则另一个将注册时间戳记。然后，如果有任何更改，更改发生的时间将记录在H列的右列。
我的问题在于，当我按下按钮启动宏i）时，调试器弹出“运行时错误1004。对象'_application的方法'undo'失败”，导致宏ii）停止工作（即停止在感兴趣的栏中记录价值发生变化的时间）。调试器突出显示的代码行是“ Application.undo”
说实话，我对过程有点迷茫。
免责声明：那里的大多数注释都可以使我了解代码的实际工作方式。非常感谢为这两个小组做出贡献的所有人。

我希望两个宏同时工作。
