# Print a counter after reading the whole document [duplicate]

I'm working on a document in which I define some numbers. I want to print at the beginning the sum of all these numbers. It's something like the desired result described in this question Displaying a later value of a counter, but I could not modify that code to obtain what I want.

Here is an example of what I want

\documentclass[leqno]{article}
\newcounter{totaldepuntos}
\setcounter{totaldepuntos}{0}
\begin{document}
\thetotaldepuntos %Must print 10
\begin{enumerate}
\item \puntos{2} Blablabla %Creates an item, put the text ´(2Pt)´ and
%sum 2 to the counter totaldepuntos
\item \puntos{4} Blobloblo %Creates an item, put the text ´(4Pt)´ and
%sum 4 to the counter totaldepuntos
\item \puntos{4} Blublbublu %Creates an item, put the text ´(4Pt)´ and
%sum 4 to the counter totaldepuntos
\end{enumerate}
\end{document}

• If the counter starts at 8 and you add 10, then it has to come to 18. Why do you want it to print 10 when it is 18? – cfr Aug 20 '16 at 21:19
