[Closed] Index out of bounds?

I’m trying to create a script that would create helpers at each cv of a nurbs surface.

 
nSet = getNURBSSet $ 
for i in 1 to nset[1].numCVs.y do
(
for k in 1 to nset[1].numCVs.x do
(
 
newPoint = point size:20 cross:false box:true wirecolor:blue
newPoint.pos = (getCV nSet[1] i k).pos 
 
)
)

This seems to work for surfaces that don’t have closed rows or columns, but as soon as I close the rows, I get this error –

– Runtime error: NURBSSet object index out of bounds: 1

In the help, it says CV indexes are 1-based. What does that mean? Is there another way to get the CV position?
