# Cleveref doesn't find the label

The following code gives me as reference the section and not the signpost. It is probably a beginner's mistake.

\documentclass{article}

\usepackage{tikz}
\usepackage{mdframed}

\newcounter{signpost}%
\newenvironment{signpost}[1][]{%
\stepcounter{signpost}%
\ifstrempty{#1}%
{\mdfsetup{%
frametitle={%
\tikz[baseline=(current bounding box.east),outer sep=0pt]
\node[anchor=east,rectangle,fill=blue!20]
{\strut Summary~\thesignpost};}}
}%
{\mdfsetup{%
frametitle={%
\tikz[baseline=(current bounding box.east),outer sep=0pt]
\node[anchor=east,rectangle,fill=blue!20]
{\strut Summary~\thesignpost:~#1};}}%
}%
\mdfsetup{innertopmargin=10pt,linecolor=blue!20,%
linewidth=2pt,topline=true,
skipabove=6pt, skipbelow=6pt, nobreak=true,
frametitleaboveskip=\dimexpr-\ht\strutbox\relax,}
\begin{mdframed}[]\relax%
}{\end{mdframed}}

\usepackage[noabbrev]{cleveref}
\crefname{signpost}{summary}{summaries}

\begin{document}

\section{Hello Stackexchange}

This is some text.

\begin{signpost}[This is a summary]
This is a summary of the above text.
\label{signpost:MWE}
\end{signpost}

In \cref{signpost:MWE} you see \ldots

\end{document}


What do I need to change in order to get the "In signpost 1 you see..."

You just have to change \stepcounter{signpost} to \refstepcounter{signpost}. The latter makes your signpost counter the one used by the reference mechanism.
