[Closed] string function problem

Hi. Wrote this code as a custom attribute to be executed as a str but the reset button doesn’t work even tho it is placed on the ca, because as it doesn’t recognize ‘morphs_used’ (undefined), even tho the code places the sliders on the custom attribute as expected and morph used is of global scope.

 
 
fn  placeParameters  ctrlsplines =
(
 --ctrl = $
 ctrlcentre = getnodebyname ctrlsplines
 
 --morphs_used = #("lLwrLipUp")
  if ctrlcentre.modifiers[1] != undefined then 
   
  ( deleteModifier ctrlcentre  1)
 
 addmodifier ctrlcentre (EmptyModifier ())
   attdeff = ""
 attStr = ""
	attStr += "attdef = attributes facialctrl
"
	attStr += "(

 attStr += " parameters facialctrl rollout:Weights

 attStr += " (

 for i = 1 to morphs_used.count do
