Add Table Valued Parameter to a stored procedure

Question

I have a stored procedure that voids an invoice and puts the items back into inventory and makes available the payment that was used to apply to this invoice... I would like to be able to do all this for a number of invoices at a time using a table valued
parameter how would I be able to do it?
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

I didn't look too close into your code, so I just translated your code as is into TVP.
