ISA - Display subTotal1 - 6 of IPC in jsp page

Please help.

I am trying to display on the order.jsp the IPC objects subTotal1 through 6. I can see how to display the objects like netValue or TaxValue but I would like to also add some new lines in and display subTotal 1 through 6. I would like to to this at header level and item level.

Can somebody tell how this is possable.
