Thank you very very much Michael.

I'll try the changes tonight after work.

I also noticed that about line 33, function Update(...,...,...,obj)
that I have "obj" instead of "powerConeSpiral"
the "obj" isn't used, so seems to be superfluous???
Changing the "obj" to "powerConeSpiral" just caused an error...

On other scripts, like eggOvoid, with your helpful preset code, the sliders worked fine, without the changes.
So I do not understand...
