Formatting content in vbcsript adding new line

In ArcMap labelling, I need to parse the label into Customer Name and its account number with the account number appearing after new line:

I used the code vbNewLine and it worked fine.

[CUBAOmeters.CUSTOMER] & vbNewLine &  [CUBAOmeters.CAN] 


Creating a new field with attributes incrementing by 1

pre-logic script code:

def autoIncrement( ):
 global rec
 pStart = 1 
 pInterval = 1 
 if (rec == 0): 
  rec = pStart 
  rec = rec + pInterval 
 return rec
