LaTeX Error: Something's wrong--perhaps a missing \item
This error appears when you have forgotten to include an \item
command. It can also appear from trying to use lists inside a table incorrectly.
Common Causes
Forgetting to write \item:
The most basic example of this error is where you have told LaTeX that you are going to be writing a list, but you have not labelled your list entries with \item
tags. An example of this is shown below
\begin{itemize}
This is the first entry in our list
\end{itemize}
Here, you have told LaTeX that you are writing a list by using the itemize
environment. The mistake that is made is that you haven't labelled your list entry with \item
. This will generate the error shown below:
main.tex, line 6
See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.6 \end{itemize} Try typing <return> to proceed. If that doesn't work, type X <return> to quit.
The correct way to write this list is:
\begin{itemize}
\item This is the first entry in our list
\end{itemize}
See here to learn more about how to make different types of lists in LaTeX.
Writing lists inside tables incorrectly:
This error will also appear if you try to number cells within a table using lists, as shown below.
\begin{tabular}{l}
\begin{enumerate}
\item This is item number one\\ \hline
\item This is item number two
\end{enumerate}
\end{tabular}
This is a mistake, as lists cannot be used to number table cells in this way. One way to solve the problem above would be to create a counter. This can be done by including
\newcounter{rownumbers}
\newcommand\rownumber{\stepcounter{rownumbers}\arabic{rownumbers}}
in the preamble to your document (see here). You can then write the above example as
\begin{tabular}{l r}
\rownumber & This is item number one\\ \hline
\rownumber & This is item number two
\end{tabular}
