[Closed] Animation copy script won't work on multiple selection

Hey folks, I’m new to MAXScript and have created a simple bit of code to copy an object’s animation and apply it to a new bone, which it is then skinned to.

Here’s the code:

gunPart = $
gunBone = bonesys.createbone [0,0,0] [10,0,0] [1,1,1]
gunBone.height=3
gunBone.width=3
gunBone.name = gunPart.name + "Bone"
gunBone.position.controller = copy gunPart.position.controller
deleteKeys gunPart.position.controller
gunSkin=(skin())
addModifier gunPart gunSkin
skinOps.addBone gunPart.modifiers[#Skin] gunBone 1

To to make it work with multiple objects that have been selected I just added this to it:

for i = 1 to selection.count do
(
	select selection[i]
	gunPart = $
	gunBone = bonesys.createbone [0,0,0] [10,0,0] [1,1,1]
	gunBone.height=3
	gunBone.width=3
	gunBone.name = gunPart.name + "Bone"
	gunBone.position.controller = copy gunPart.position.controller
	deleteKeys gunPart.position.controller
	gunSkin=(skin())
	addModifier gunPart gunSkin
	skinOps.addBone gunPart.modifiers[#Skin] gunBone 1
)

And it just gives me this error:

-- Error occurred in i loop; filename: C:\Work\3dsmax\MAXScript\boneCreatorMulti.ms; position: 57; line: 3
--  Frame:
--   i: 2
-- No ""select"" function for undefined

I don’t know what I’m missing here and any help would be greatly appreciated.
