添加文本和变量

我不知道任何 LaTeX 代码，但我不知道为什么它如此难以编辑...:( 我不断收到此错误：“未定义的控制序列”。

这是压缩文件：https://www.dropbox.com/s/oqs85dacw8yl3ul/latex-rechnung.rar?dl=0

这是我的代码：

我想在“Leistungszeitraum:”下方添加两个可以自行设置的日期。因此有两个变量\performanceStart和\performanceEnd可设置，然后将它们粘贴到红色矩形所在的位置，中间有一个“-”或单词。

我现在拥有的

非常令人沮丧的 LaTeX......

答案1

好了，您已经定义了两个命令\performaceStart和\performaceEnd。

然后您可以简单地将它们添加到如下定义中location：

\setkomavar{location}{%
      \\[\baselineskip] \\[\baselineskip]
      \flushright\small \invoicenr \invoiceReference\\[5pt]
      \customernr\\
      \customerNumber\\[5pt]
      \performanceDuration\\ 
      \performaceStart{} -- \performaceEnd % <====================================
    }
