Hi David,

I could not get through the example file: here is what I get:
%%%%% begin error report:

! Missing number, treated as zero.

%%%%% end error report

I tried also the short example I sent you today, 
but I get the same result. Is there a 
transmission error in your file? (I should say 
that everything is fine if one doesn't have a 
\placeformula).

Finally, if I am not being too demanding, at the 
end of t-rsteps.tex, in your example of how to 
use the command (for the user's convenience) 
could you please incude all the possibilities of 
using the Step commands? that is instances of:

\OnlyStep[1]{\item something}
\FromStep[2]{\item something}
\AfterStep[3]{\item something}
\UntilStep[4]{\item something}
\HighlightStep[5]{\item something}
\NextStep[1]{\item something}

(Actually it seems that there is also a problem with \NextStep)
Best regards: OK
