I've made a patch to compare 2 numbers and calculate the range between them. It works! ...but strangely not always - sometimes it outputs the wrong number, like something got stuck along the way and a number that I gave in previously is compared to the new #1 or #2.

I can't seem to find out what's the problem, although I have a hunch it occurs more often when I use the same numbers (like 0 and 0) or make use of one or two negative numbers. To me it occurs just too random to make sense, anyone has an idea what could be wrong?

Dang!!! Can't believe I forgot about the hot-cold inlet thing!

Oh well... should be solved now (I think...) and I've gained some more insight. If anyone has some patch for summoning intelligence please let me know

This is a classic case of needing triggers to help the evaluation order. But even with triggers your algorithm has a bug. If two vaues are the same then the left hand branch does not update so the subtraction uses the last value that appeared and causes an error.

I have attached a patch using [min] and [max] that might help you.

Thanks a bunch! Didn't know about the min/max objects yet and this sure helps.
