[Closed] Custom Attribute Param Value

Hey tehre… so I have this code…

rollout curl "Hand Curls"
	(
		slider indexcurl "Index"  range:[-90,90,0]
		slider middlecurl "Middle"  range:[-90,90,0]
		slider ringcurl "Ring"  range:[-90,90,0]
		slider pinkycurl "Pinky"  range:[-90,90,0]
		slider thumbcurl "Thumb"  range:[-90,90,0]
		
		on indexcurl changed val do
		(
			 local names = custAttributes.getDef $ handControls
			 messagebox(names[indexBone1].value + val) -- Testing to see if it would call the param
		)
	)

I am having trouble curling these fingers… that is why I established this. I am trying to have independent influences on fingers. For say: You can move each joint individually while controling it as a whole under another contorl. I was looking @ PEN_Attrib. Holder… That gave me a hint of what to do, but I don’t really know how to call parameters in custom attributes… I know what we use

local names = custAttributes.getDef $ handControls

To get the CA, but then what do i do to get a parameter value and alter the value?

Thanks,
Jon
