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:


\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.

if you want a chain of commands, use a syntax like this:

\startsetups what:ever
  \command 1
  \command 2

which you can then call with
