錯誤失控參數，遺失 }

Question

我突然在幾個數字中出現了一些失控的爭論，但我不認為我錯過了什麼。

這些是我的腳本行：

\begin{figure}[h] 
    \centering
    \includegraphics[width=0.9\textwidth]{Figures/00-figures/metylblauw.jpg}
    \caption{Results of methylene blue tests on filter paper.}
    \label{fig:filterpaper}
\end{figure}

這是錯誤訊息：

Runaway argument?
