I have a counter that I'd like to reset

\newcounter \nuggetnumber \def \numberofnuggets{0}

\definehead [nugget] [section] \setuphead [nugget] [number=yes,page=yes, before=\increment \nuggetnumber, after=\savecurrentvalue \numberofnuggets{\countervalue{nuggetnumber}},] % LO as nugget

This counts the number of nuggets.. and seems to work fine.

But when it gets to an episode it should reset....so, maybe like this

\definehead [episode] [title] \setuphead [episode] [numberstyle=bold, textstyle=cap, number=yes,before=\resetnumber[nuggetnumber]]

Here, you need at least a pair of braces (actually, I'm surprised your code doesn't give an error): \setuphead [episode] [numberstyle=bold, textstyle=cap, number=yes,before={\resetnumber[nuggetnumber]}] It's better, however, not to use low-level commands, but context syntax: \definelabel[nuggetnumber][headstyle=normal,way=bytext,prefix=no,text=] \definehead [nugget] [section] \setuphead [nugget] [number=yes,page=yes, before=\incrementnuggetnumber] \definehead [episode] [title] \setuphead [episode] [numberstyle=bold, textstyle=cap, number=yes,before=\resetnuggetnumber] context does all the housekeeping for you, no need to savevalue etc.

while I am at it, I am equally unsure how to reset the numberofnuggets accumulator, which should also be done on meeting the episode structural element - I'd like to insert a whole chain of commands in the before=...'

if you want a chain of commands, use a syntax like this: \startsetups what:ever \command 1 \command 2 ... \stopsetups which you can then call with \setuphead[argl][after=\setups{what:ever}] HTH Thomas
