How to solve py_post.IndexError: Node scalar at 5 does not exist?

aurea.inurritegui
I have a python program to obtain contact_status from nodes (I use p.node_scalar(i,j)) in the surface of a .t16 model.
I am using version 2019.
Node scalar 5, is the contact status. However changing this number continues showing the error...
 
I keep obtaining the error mentionned above, can anyone help me fixing the error?
 
Thak you very much!

    You are probably using the incorrect index for the extraction of the contact status. A simple way to confirm this, and to find out the correct index, is to add this snippet of code somewhere in the routine:
     
       nns = p.node_scalars()
       print("Found ", nns, " node scalars ")
       for j in range(0, nns):
           print ("index: ",j," label: ", p.node_scalar_label(j))
     
    The correct index is likely 15.
