can you find modifier copy code erro ?

I'm trying to solve your other post ... below is part of your problem.
example...

modCp = #()
for z in selection do
(
	if z.modifiers != 0 then (
	for h = 1 to z.modifiers.count do 
	(if classof z.modifiers[h] == uvwmap do (insertItem (copy z.modifiers[h]) modCp h))
	)
)

your code is very good
but i can't understand well still

i made code again
work is good
but there is problem . that is to be copy many uvwmaps in 1 object
i would like to be copy 1 times

in advance , thank you

S=#()
tst = #()
sel=selection as array

modCp = #()

for z in sel do

(

for o in geometry do

(

if z.name == o.name then

(

if z.modifiers != 0 then (
for h = 1 to z.modifiers.count do
(if classof z.modifiers[h] == uvwmap do

tmp = copy z.modifiers[#UVW_Mapping]
addmodifier o tmp
--deleteModifier o o.uvw_mapping

)

)

else
(

)

)

)

)

I do not understand...

at any way thank you
