And another question: We have 2 sliders, each with a value range of 1 to 12. We also need the combined maximum value of both sliders not to exceed 1

And another question:  We have 2 sliders, each with a value range of 1 to 12.  We also need the combined maximum value of both sliders not to exceed 12.  Is this possible?

For example:

If slider #1 is set to a value of 8, then slider #2 can not exceed a value of 4 (#1 + #2 ≤ 12), or conversely slider #1 could not be set to a value greater than 8, if slider #2 already had a value of 4

It's not possible to conditionally limit the maximum amount in sliders.

The only workaround I see is to create multiple sliders and show each when needed.

For example, you have one slider that is up to 12, and then you have multiple sliders where one is up to 1, then the second one is up to 2, then the third is up to 3 and so on.

So when you select in first slider 8 for example, that will show the slider which limit is up to 4.

When you select 10 in the first slider that will show slider which limit is up to 2.

Does that make sense?

Let us know if you have any further questions.
