Looking at the code again, you actually don't need to go the approach of
passing an argument. The global "amp" should work. You just need to not be

The control works (when I do a mouse-drag on the slider bar), but the slide

I suspect what you are having difficulties with has to do with your use of
a global variable "amp". It is going to be completely unlikely that updates

I am controlling a simple animation with a slider, successfully. A mouse
drag updates the parameter correctly but the slider-bar position is not
updated.
If "samp" is a slider, the c
