I was trying to figure out how to allow Dynamics to calculate the taxes automatically.

In order to make this work, I had to do this:

 .SUBTOTAL = dblSubtotal
.FREIGHT = 0
.MISCAMNT = 0
'.TAXAMNT = 0
'.FRTTXAMT = 0
'.MSCTXAMT = 0
'.TRDISAMT = 0


'this is '1'
.CREATETAXES = eConnect9.GP9.SOP.taSOPHdrIvcInsert.CREATETAXESType.dynamicsHandlesTaxes
.DOCAMNT = dblSubtotal

Note that SUBTOTAL = DOCAMNT, and that most everything else is commented out
