Hi,
I am trying to create a new vif with the new-nanetvif command.  I have an execl spreadsheet like so:
Interface Name(A)          Interfaces(B)             Type(C)     LB(D)
ifgrp-nas                        e0a e0b                    lacp            ip
ifgrp-iscsi                      e1a e1b                     lacp           ip 
I am reading each item on a row into a variable and running the new-nanetvif command.  The problem I have is that the interfaces (e0a, e0b) aren't not being configued on the vif.  It seems that the command is wanting a string array; but when I provide an array it throws an error.  
Sample code below
# Get ifgrp worksheet and process
$ifgrp=$ExcelWorkBook.sheets.item(6)
$intRowMax=($ifgrp.UsedRange.Rows).count
  for($intRow=2;$intRow -le $IntRowMax;$IntRow++)
{
    new-nanetvif  $ifgrp.cells.item(2,"A").value2  $ifgrp.cells.item(2,"B").value2  $ifgrp.cells.item(2,"C").value2  $ifgrp.cells.item(2,"D").value2
 }
Any help much appreciated!
Cheers
