Re: stacking

Thank you Aditya! Your solution works for me. I added the counter to 
your code:

\directlua{
counter = 1
}

\startbuffer[Q\directlua{tex.print(counter)}]
\startstackingsteps[1,{1:2}]
    \stacking[1]{First Question}

    \stacking[2]{First Answer}
    \page
  \stopstackingsteps
\stopbuffer
\directlua{counter = counter + 1}

\startbuffer[Q\directlua{tex.print(counter)}]
\startstackingsteps[1,{1:2}]
    \stacking[1]{Second Question}

    \stacking[2]{Second Answer}
    \page
  \stopstackingsteps
\stopbuffer
\directlua{counter = counter + 1}

\starttext

\dorecurse{2}{\getbuffer[Q\recurselevel]}

\stoptext
