One of my favourite errors. Everytime it occurs I'm a bit puzzled, as
I've no general solution for this. I can only tell you what I do in such
a case.
- check every parameter of the expression
If the expression itself is ok
- check the correct grouping of prior commands (boxes, conditionals,..)
- try to calculate the expression before you pass it
\newcount\Myscale
\Myscale\numexpr1000\LPscale\relax
..[scale=\the\Myscale]
But in the end it is more try and error than a systematic action.
If there is a more general approach to solve this, I would be happy to
hear it.
Greetings, Peter
