You can't use `\numexpr' in horizontal mode. > 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.
