You’re correct that the slider does not accept variables. The only variable that does accept other variables is the expression.
We think we could modify the slider for this to work, but here is a trick you could use now to get essentially the same effect …
- leave the slider in the default of zero to one
- create an expression variable
- set the min and max (either in the expression or as separate variables)
- set the expression to (max-min)*slider+min
In this example, the variable ‘number’ will change when you move the slider between the min and max.
