I want to define a macro to add an automated symbol explanation under an equation. I have to use pre-defined glossary entries because the glsentrycurrent does not allow to add new glossaries in the document. To add the automated legend I define the newcommand addLegeds which should basically loop over all comma separated strings passed as an argument and check if they have been used befor. If all of them were used befor no legend should be added. The macro works exept that as soon as I use the gls or glsdesc macros, I get the following errors:

Argument of @tempc has an extra }. addLegends{test1,test2} 

File ended while scanning use of @tempc.

Missing endcsname inserted. addLegends{test1,test2}

Paragraph ended before @tempc was complete. addLegends{test1,test2}

Undefined control sequence. addLegends{test1,test2}

The following macro has been used:

makeatletter

newififshowleg

newcommand{addLegends}[1]{%

    showlegfalse

    @for@tempa:=#1do{%

        ifnumequal{glsentrycurrcount{@tempa}}{0}{showlegtrue}{}}%

    ifshowleg  %

        with: % 

        begin{conditions} %

            @for@tempb:=#1do{ %

                ifnumequal{glsentrycurrcount{@tempb}}{0}{ %

                    gls{@tempb} & glsdesc{@tempb}\ %

                }{}}%

        end{conditions} %

     else fi %

}

makeatother

And this is a reduced version of the latex document:

usepackage[toc]{glossaries}

glsenableentrycount

% MACRO

    newglossaryentry{test1}{name={test1},description={TEST1}}

    newglossaryentry{test2}{name={test2},description={TEST2}}



begin{document}

addLegends{test1,test2}

begin{end}

Does anybody know what is causing the error?

Thanks,
Markus
