is it possible to calculate 2 sublist fields that are not items? I have a custom sublist that has a child/parent relationship with a sales order. I would like to have 2 fields calculate and have that answer populate the 3rd field. I can do this with item fields via sutiescript but am a little lost when it comes to a custom sublist. Would I still use

nlapiGetCurrentLineItemValue('mysublist','mysublistfieldname')

?
