Want line item total in invoice to not show up until other information is entered.

I am creating an invoice document in acrobat.  I have set up each line for input of quantities with a price and then total in the right column.  The right column always shows $0.00 in the total box, even when nothing it input into the quantity or price box.  Is there a way to make the $0.00 hidden until those two boxes are filled?  I am ok with the subtotal, tax rate, and balance staying as zeros... I just want the option to not have a ton of zeros if I only end up using one or two lines.  

I am using the Adobe CC Acrobat to create this document.
