- 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.
