我上面的Excel-VBA代码有什么问题？

Question

我希望VBA实现的功能的简要说明：我试图从两个Excel电子表格中导入数据，然后比较每个列表中的数据以找到每个列表中的缺失元素，然后在缺少数据行时突出显示该数据行。

Well there is a certain kind of order required to run Differences. Import_buttonx has to be called before Differences can be called. So you get an out of index because stringOfSheet(1,2) probably ha no value. It's probably nil. You can check while debugging through your code.
