Suppose you want h to slide from a high of 2 to a low of 0, in that order.

There are two ways to do this.

1.      In the equation pane type

h=-n

Label the slider n, and have n slide from 0 to 2.

2.     In the equation pane type

h=slider(0,2)

In this second way, you have to move the slider by hand.

Thank you Beth and all others who gave some suggestions, all useful of course.

I will try to introduce h=-n and see what happens, but I know that some, not all, will feel uncomfortable to have to write h=-n. "Why? Well, you know, because the slider does not go from 2 to 0"

I am sometimes asked to remedy some problems in the classroom (of younger teachers) and these kind of questions arise there.
The problem I was referring to is that when trying to explain A it is not good practice to be forced to introduce and explain B to explain A.

So I would like to have an interface that is so unobtrusive as possible (=no fixes, just logic).

Ah well, deep gratitude to all of you!

All the best
