[Closed] fn compile error

Hey guys,

This may be a simple issue but I don’t understand it.

I wrote a recursive function based off this thread that goes through a selection, looks for named list controllers, and sets them active.

The function works but only if I evaluate the the function inside the function first, and then evaluate the entire function as a whole. Can anyone explain why that is and how I can avoid it?

/*
Example Usage:
Select objects and run:
setActiveList "animation" -- sets all list controls named 'animation' to active
setActiveList "zero" -- sets all list controls named 'zero' to active
*/

fn setActiveList keyWord =
(

fn RecurseSubAnims o active =
(
  	-- do something
	listTypes = #(float_list, position_list, rotation_list, scale_list)
	for j = 1 to listTypes.count do 
	(
		if (isKindOf o.controller listTypes[j]) == true do 
		(
			for k = 1 to o.controller.count where (o.controller.getName k) == active do o.controller.setActive k
		)
	)-- end j loop 
		
  	-- recurse
  	for i = 1 to o.numsubs do RecurseSubAnims o[i] active
) -- end RecurseSubAnims

	for h in selection do
	(
		RecurseSubAnims h keyWord
	)-- end h loop

) --end fn 

If I try and evaluate the above code I get this error:

-- Compile error: No outer local variable references permitted here:  RecurseSubAnims
--  In line:   	for i = 1 to o.numsubs do RecurseSubAnims o

But if I evaluate RecurseSubAnims separately I get no errors. Once that’s defined I can evaluate the entire thing with no errors.

How do I need to write the code so that I can define the entire thing in one pass?

Thanks for any help!
