I’ve been trying to create a slider that shows a number in a box based upon how much you drag on the y coordiate.

I’m nearly there! but the number in the box is not correct

I want the value in the box inverted, so as you drag down the number decreases and as you drag upwards the number increases so it matches the graph coordinates. Any ideas?

I just noticed that clicking on the plus and minus bottoms is a bit broken. It doesn’t allow you to go all the way to the top or bottom but hopefully you can sort that out from here.
