I'm using a longtable for the nomenclature produced by the nomencl package. Here, the longtable serves as a tabluar replacement. Unfortunately, the usage confuses the totalcount package resulting in an uncorrect table count.
MWE:
\documentclass{report}
\usepackage{longtable}
\usepackage[figure,table]{totalcount}
\begin{document}
\verb|\totaltables| is \totaltables, but should be 2.
\begin{table}One\caption{Table One}\end{table} % ONE
\begin{table}Two\caption{Table Two}\end{table} % TWO
\begin{longtable}{cc}
Long & Bla
\end{longtable}
\end{document}
Result:

longtabledoes not have alongtablecounter but uses the standardtablecounter. – Mar 19 '15 at 15:57totalcountpackage, but you can check this question. Looks like it could help you. – TonioElGringo Mar 19 '15 at 16:10
