Thank you both.
I got as far as \dimexpr (expressions) page in the Wiki, and all the words
made sense, more or less, but not the whole.
In case anyone else find this useful, I have success with Wolfgang 2 and 3,
with (2) being the simplest....but that may just be the fit to my brain.
It's building stacked progress bars for documents with subsections, in case
anyone searches this- colours and prettification to follow!

Sorry. me again...and I have been all over the wiki, mailing lists and manuals...
I have this:
\setlayer [progresssteps] % name of the layer [hoffset=904 px, voffset= 28\nuggetnumber px] % placement (from upper left corner of the layer) {\stepstack} % the actual contents of the layer
And I am hoping that as I increase nuggetnumber the voffset of the layer will be 28*nuggetnumber
Variant 1:
\newdimen\baseoffset \baseoffset=28px
\setlayer[…][voffset=4\nuggetnumber]{…}
Variant 2:
\def\nuggetnumber{4}
\setlayer[…][voffset=\dimexpr28px*\nuggetnumber\relax]{…}
Variant 3 (what i suggest):
\definemeasure[baseoffset][28px] \definemeasure[verticaloffset][\dimexpr\measure{baseoffset}*4\relax] % replace “4” with your own factor
\setlayer[…][voffset=\measure{verticaloffset}]{…}
