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 I am setting nuggetnumber like this for the moment: \def \nuggetnumber{3} (in the other dev document it is the result of counter, so set dynamically) and this in the text \nuggetnumber which compiles to '3', so I assume the assignment is good to go. varying both nuggetnumber and the scale factor (28) shift the layer up and down, but not in a way that suggests that 28\nuggetnumber is being evaluated as a product (so a scale factor of 7 and a nuggetnumber of 2 do not give the same output as a scale factor of 2 and a nuggetnumber of 7). So I am led to think that there is something in the evaluating that is going wrong - data types / units? (if I hard code in the results I am expecting, say 28 px, 56 px or 84 px then I get exactly what I want... Thanks, as ever (Same result in ConTEXt ii or iv) Ian

\def \nuggetnumber{3}

and this in the text
\nuggetnumber
which compiles to '3', so I assume the assignment is good to go.

If you expect a product you should tell ConTeXt you want a product. You don't do that with "28\nuggetnumber px". Check out http://wiki.contextgarden.net/Expressions I think "\dimexpr\nuggetnumber*28px\relax" should get you there, but I'm not sure (untested). Stefan

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}]{…} Wolfgang
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!

\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
