[Kickflip]

Hi,

I have a simple code:

Code: Select all

Code, edit and compile here:

1

bla bla bla \ref{adhaesion_hysterese} bla bla bla. 
\begin{figure}[H]
    \centering
    \includegraphics[width=0.5\linewidth]{Adhaesion_Hysterese_Pic_Name}
    \caption{bla bla bla (\textsc{Grosch}{Grosch.1963})}            
    \label{adhaesion_hysterese}
\end{figure}

Run LaTeX here

it says: Reference 'adhaesion_hysterese' on page 3 undefined on input line 21


why?

Run LaTeX here

It seems that you are doing actually something different, and that copied code snippets don't show it. Perhaps post a full example, reduced to the minimum, that brings the error, as I did here.
