运行时错误'91'：对象变量或With块变量未设置Catalog Mailmerge

Question

我正在尝试从Macropod上使用该目录进行邮件合并的教程，但是我不断收到我不理解的错误。

我已经走到了教程的最后一步，我想尝试实际的电子邮件合并。我在目录/目录mailmerge主文档中使用下面的代码创建了一个宏，并将该文档保存在与“电子邮件合并主文档”相同的文件夹中。但是现在当我运行宏RunMerge时出现错误

  

运行时错误'91'：对象变量或未设置块变量

当我单击debug时，它将突出显示.Paragraphs(1).Range.Delete中的第一个Sub EmailMergeTableMaker(DocName As Document)。这是我第一次必须对VBA做任何事情，而且我不知道如何解决这个问题。

错误是什么意思？我猜想这行引用了一个未正确设置的变量，但是我只是从教程中复制了代码，而且不知道正在引用哪个变量。
